Saint Catherine’s Monastery: An Ark in the Wilderness

Father Justin with his cousin (and friend of mine), Bunny Gibson

The following is the lecture delivered on Tuesday night, November 8, 2011 at a symposium on the St. Catherine’s monastery library and the significance of the Sinai manuscripts, hosted by Dr. Daniel B. Wallace and the Center for the Study of New Testament Manuscripts at the Hope Center in Plano, Texas. 

 

The Earliest References

1 The history of a Christian and monastic presence at Sinai begins not in Byzantine times, but extends back into the years of late classical antiquity. One of the earliest narratives to come down to us from that time is Ammonius’s account of the Forty Martyrs of Sinai and Rhaithou. There, we read about monks who had been living in the Sinai deserts ‘for forty years, and for fifty, and for sixty, and for seventy years, who have dwelt in the same place.’ We also read about a monk named Moses, who was admired by all for his zeal and for his grave manner of life. 2 ‘A certain Moses, having adopted the discipline of monasticism from his youth, practised monasticism for seventy-three years in that mountain from which springs of water issued.’ ‘And this saint, from the time that he took the habit of Christ, ate no flesh, but he ate dates only.’ ‘The food of that saint was a few dates, and water only. And he never tasted wine. And his dress was of compressed palm fibre. And he loved silence more than all men.’ From the many miracles that God wrought through him, all the inhabitants of Pharan had come to believe in the Holy Trinity, and received holy Baptism.[1]

I was in Rhaithou in July a few years ago. The temperature registered 118 degrees Fahrenheit. A hot and searing breeze blew from across the Red Sea. It was yet another small insight into the heroism of the monks who lived there in centuries gone by.

3 The historical events described by Ammonius allow us to date his account to the year 373.[2] Thus when he describes elders who have dwelt there as monks for sixty, for seventy, and more years, we understand that there was already an established monasticism at Sinai and Rhaithou at the end of the third and the very beginning of the fourth century, when persecutions were still raging against the Christians. Even then, there dwelt ascetics in the Sinai deserts who were established in virtue, who had attained to the pinnacles of prayer and spiritual graces.

4 Another important early text is the travel account of Egeria, who made a pilgrimage to Jerusalem, after which she continued on to Sinai, around the year 383. She worshipped at the chapel on the peak of Sinai, and at the cave of the Prophet Elias below the peak, after which she descended into the valley, to the Church of the Burning Bush. 5 She writes, ‘there are many cells of holy men and a church on the spot where the bush stands; and this bush is still alive today and gives forth shoots.’[3] The monks celebrated the Liturgy for the pilgrims, and read for them those passages of scripture concerning the events that had taken place at each site. They also presented them with fruits from their gardens.

From the fourth century, Sinai was a place where monks lived in solitude and austerity. But it was also a place of pilgrimage, and these two strands have continued throughout the history of the area, even to our own day.

The Sixth Century

6 In the sixth century, the Emperor Justinian ordered the construction of a basilica and high surrounding walls, that have stood ever since. This was done to honour this holy place, and to protect the monks who lived there. The church is remarkably well preserved. Not only are the columns, the capitals, and the walls intact, but the central doors into the nave and the heavy ceiling beams also date from the sixth century. And the focal point of the church is the mosaic of the Transfiguration, one of the most profound works of art from that time. 7 The lintel over the door into the nave bears this inscription,

+ Καὶ ἐλάλησεν κ(ύριο)ς πρὸς Μωυσῆν ἐν τῷ τόπῳ τούτῳ λέγων· ἐγὼ εἰμὶ ὁ θ(εὸ)ς τῶν πατέρων σου, ὁ θ(εὸ)ς Ἀβραὰμ κ(αὶ) ὁ θ(εὸ)ς Ἰσαὰκ καὶ ὁ θ(εὸ)ς Ἰακώβ. + Ἐγὼ εἰμὶ ὁ ὤν +[4]

+ And the Lord spake unto Moses at this place, saying: I am the God of thy fathers, the God of Abraham, and the God of Isaac, and the God of Jacob. + I AM THAT I AM +

8 We can date the completion of the basilica to within a few years, from inscriptions carved on the beams. The seventh beam, counting from the west end, bears an inscription meant to be visible to those entering the nave,

+ Ὑπὲρ μνήμης κ(αὶ) ἀναπαύσεως τῆς γεναμένης ἡμῶν βασιλίδος Θεοδώρας +

+ For the memory and repose of our late Empress Theodora +

The eighth beam bears the inscription,

+ Ὑπὲρ σωτηρίας τοῦ εὐσεβ(εστάτου) ἡμῶν βασιλέως Ἰουστινιανοῦ +

+ For the salvation of our most pious Emperor Justinian +

The inscription on the one beam commemorates the Empress Theodora as having passed away, while the inscription on the other commemorates the Emperor Justinian as still living. We know that the Empress Theodora died in the year 548, while the Emperor Justinian died in 565. These two dates provide the terminus post quem and the terminus ante quem for the completion of the basilica. Is it possible to make the dates even more precise?

9 Procopius, in his work On Buildings, mentions that at the base of the mountain where Moses received the Laws from God, the Emperor built a very strong fortress, with a church dedicated to the Mother of God, to enable the anchorites who dwelt there to pass their lives therein praying and holding services.[5] Many scholars feel that Procopius’ On Buildings was completed in the year 554/5, though others have argued for the date 559/60.[6] Even the latter would allow us to narrow the date for the completion of the basilica to within a span of twelve years.

10 A Greek plaque on the west wall of the monastery refers to the completion of the monastery in the thirtieth year of the reign of the Emperor Justinian, which would be the year 557. Although this particular inscription is not early, it may have been based on earlier records. The date indicated is in keeping with the other dates that we have seen.

11 There is one last inscription to be considered. The mosaic of the Transfiguration of Christ includes this dedicatory inscription,

+ Ἐν ὀνόματι π(ατ)ρ(ὸ)ς κ(αὶ) ὑ(ιο)ῦ κ(αὶ) ἁγίου πν(εύματο)ς· γέγονεν τὸ πᾶν ἔργον τοῦτο ὑπὲρ σωτηρίας τῶν καρποφορησάντ(ων), ἐπὶ Λογγίνου τοῦ ὁσιωτ(άτου) πρεσβ(υτέρου) κ(αὶ) ἡγουμ(ένου) +

+ Σπουδῇ Θεοδώρου πρεσβ(υτέρου) κ(αὶ) δευτ(εραρίου), ἰνδ(ικτιῶνος) δϊ +

+ In the Name of the Father, and of the Son, and of the Holy Spirit. This entire work was executed for the salvation of those who had offered the fruits, by Longinus the most pious presbyter and abbot +

+ The work of Theodore presbyter and deuterarius, indiction fourteen +

This same Abbot Longinus is portrayed in one of the medallions of the mosaic, with a white square placed behind his head as an indication that he was still living at the time. In the years we have been considering, the fourteenth indiction would have fallen during the years 550/1, or 565/6. The latter date is the more probable for the completion of the mosaic.

The entire subsequent history of Saint Catherine’s Monastery may be said to have been written between the ruling lines that we have now traced.

 The Sinai Library

12 The Persians sacked Jerusalem in 614, but it was not worth their while to come to this remote site. Its very isolation protected it. Islam came to the area in the year 632. But Moslems also revere Sinai as a sacred mountain, and the monks found a way to live in peace with their new rulers. The monastery continued as it had of old. Ascetics came to this desolate wilderness and reached great spiritual heights. Their writings have been treasured by Christians throughout the world ever since.

13 The most important book to be written at Sinai is called The Ladder of Divine Ascent, in which the author took the ladder that Jacob saw extending from earth to heaven as the motif for the spiritual life. Saint John of the Ladder was abbot of Sinai in the late sixth century. Before being elected abbot, he had lived as an anchorite for forty years, during which he spent his time saying prayers and copying books. This is an indirect witness to the production of manuscripts at Sinai. Precious manuscripts were also brought to the monastery over the years.

The monastery has never been destroyed or abandoned in all its centuries of existence. The climate at Sinai is surprisingly dry and stable, the humidity averaging from twenty to thirty percent. All of this, and the diligent care of the monks, account for the preservation of many manuscripts. The Sinai library is today a remarkable treasure for the antiquity and the significance of its volumes.

14 The library contains 3304 manuscripts, written in eleven languages. These are predominantly Greek, Arabic, Syriac, Georgian, and Slavonic. The manuscripts range in content from copies of the Scriptures, services, and music manuscripts, to sermons, writings of the Fathers, lives of the Saints, and books of inherited spiritual wisdom. The library also includes medical treatises, historical chronicles, and texts in classical Greek, which is the pinnacle of the Greek language.

15 A few of the manuscripts are splendid works of art, with gilded letters and brilliant illuminations, created in Constantinople in the tenth, eleventh, and twelfth centuries, when the City was at its height as the centre of culture and devotion. But no less significant are the humble manuscripts written at Sinai, often on reused parchment, bound between rough boards, the pages stained from long use, a witness to the deprivations and austerity of Sinai, to the generations of monks who have maintained the life of devotion and the cycle of daily services at this holy place.

But perhaps we would come to a greater appreciation of the Sinai library if I could describe four manuscripts in particular, all of which have been recently studied by scholars.

Sinai New Finds Christian Palestinian Aramaic 59

16 Aramaic was the language spoken in Palestine at the time of Jesus, and there are a number of Aramaic words and phrases preserved as such in the Greek New Testament.

Καὶ κρατήσας τῆς χειρὸς τοῦ παιδίου, λέγει αὐτῇ· Ταλιθά, κοῦμι· ὅ ἐστι μεθερμηνευόμενον· τὸ κοράσιον, σοὶ λέγω, ἔγειραι.

And he took the damsel by the hand, and said unto her, Talitha cumi; which is, being interpreted, Damsel, I say unto thee, arise. (Mark 5:41)

In Saint Paul’s First Epistle to the Corinthians, he quotes the Aramaic word Maranatha, which means ‘Come, O Lord,’ or, ‘Our Lord is come’ (I Corinthians 16:22), a prayer that must have been familiar to them, and which goes back to the first Aramaic speaking Christians.

A number of manuscripts survive in Christian Palestinian Aramaic, the earliest dating from the sixth century. They are written in a Syriac script, though Syriac and Aramaic are different languages. The texts are mostly copies of the Scriptures, liturgical texts, and lives of the Saints.

Centuries ago, the Sinai manuscripts were kept at a number of different places within the monastery. Some of the oldest were stored in a room in the tower of Saint George, which projects off the north wall of the monastery. In 1734, Archbishop Nikiphoros Marthales created rooms opposite the Archbishop’s quarters for the manuscripts, and asked that they be gathered there from the various areas where they had been stored before. We know now that manuscrips that were already in a ruinous state, as well as loose leaves and fragments, were left behind in this tower room. Some time later, the roof above them collapsed. There they remained until 1975, when one monk was carrying out repairs to the tower, and came across this deposit of manuscripts. They are collectively known as the New Finds.

Among them were a number of manuscripts written in Christian Palestinian Aramaic. A manuscript that dates from the seventh or eighth centuries contains the Sayings of the Desert Fathers, number 59 in the collection. 17 One of the most beautiful is a Lectionary dating from the thirteenth century, manuscript number 41. Professor Alain Desreumaux, from Paris, is a recognised authority on texts written in Aramaic. He visited the monastery during the first week in June of last year, and spent some time studying these manuscripts. He is even now editing and publishing them, thus adding to the number of known texts in Christian Palestinian Aramaic.

Sinai Syriac 52

The writings of Dionysius the Areopagite consist of four treatises and ten letters. The four treatises are The Divine Names, The Mystical Theology, The Celestial Hierarchy, and The Ecclesiastical Hierarchy. Although these works pass under the name of the Athenian who was converted by the Apostle Paul, as mentioned in Acts 17:34, the works are not referred to before the close of the fifth century. Earlier controversies over the reliability of these writings were set aside when they were confirmed by Maximus the Confessor, and quoted by the Lateran Council held in 649. They were translated into Syriac by Sergius of Reshaina, who died in 536. In 827, the Byzantine Emperor Michael II sent gifts to Louis the Pious, among them the works of Dionysius the Areopagite, and Hilduin, the chaplain of the king and later Bishop of Paris, had them translated into Latin. In 858, Scotus Eriugena made a new translation into Latin. From this, they became known and influential in the West. These writings remain of the greatest importance even today in the Orthodox Church.

18 The oldest surviving manuscript in the world of the works of Dionysius the Areopagite is Sinai Syriac 52, a manuscript of the sixth century, that is, the very century in which these works were first translated into Syriac, and the century following their first emergence. The Hungarian scholar Istvan Perczel had edited the works of Dionysius included in this manuscript, working from the microfilm that was made by the Library of Congress in 1950. But there are areas of the manuscript that were damaged or stained, and these were illegible in the microfilm. He came to Sinai for the first time in July of last year, and was able to study the manuscript in some detail. From his reading of the original, and from the high resolution digital images that we were able to take and send him, he hopes to make a new edition of the text.

We know from the enumeration on the first folio of this manuscript that it is missing the first two quires. But an additional six folios from this manuscript turned up in the New Finds, and there are also folios belonging to this manuscript in Paris and Milan. Between all of these, the first two quires are complete, forming the Introduction to the translation made by Sergius of Reshaina.

The Codex Sinaiticus

19 The Codex Sinaiticus has been called the world’s oldest Bible. It was written around the year 325, by professional scribes using the finest parchment. It originally consisted of 740 leaves, and contained the whole Bible, from Genesis to Revelation, and in addition, two early Christian writings, the Epistle of Barnabas, and the Shepherd of Hermas. Sadly, due to Constantine Tischendorf, the leaves of this manuscript are now dispersed among four different institutions: the British Library, the library of the University of Leipzig, the State Library of Russa at Saint Petersburg, and Saint Catherine’s Monastery at Sinai. The Sinai leaves were recovered with the New Finds, and consist of twelve entire leaves, and fragments from an additional four.

Although the monastery has always regretted the loss of this manuscript, in 2005 we began a collaboration with the other three institutions, setting aside our differences to accomplish something so important: the conservation of the original leaves, and their publication, both on the internet and in facsimile, together with a complete new transcription of the entire manuscript. In this way, the leaves would be virtually reunited, and made accessible to scholars and students around the world.

20 The conservation of the leaves and fragments at Sinai was carried out in May of 2008, and the following month, scholars came from England to transcribe the texts. They read from the original leaves, sometimes backlighting them to be able to make out faded or damaged letters. But there were times when high resolution digital photographs revealed more of the text, and using these images, they could consult with other scholars about complex passages, especially those passages where there had been multiple corrections. The manuscript and transcription were posted on the internet in July of 2009, and the printed facsimile became available in January of this year.

In July of 2009, we were able to make an important announcement about this manuscript. Three years earlier, conservators completed a survey of the Sinai manuscripts, recording the state of each volume, and taking photographs of the bindings. Nikolas Sarris, a Greek from Patmos, used these photographs to study the tooling of the manuscripts. From the decorative stamps used in the bindings, he was able to reconstruct which manuscripts were bound in the same workshop, and determine whether the bindings were executed elsewhere, or made at Sinai itself.

21 He brought to my attention one of the photographs made during the survey. This was Sinai Greek 2289, and he knew from his research that it was one of a group of eighteen bindings made at the monastery in the first quarter of the eighteenth century. 22 On the inside back board, the paper lining had been partially torn away, revealing a parchment with Greek majuscule script. Was it too much to hope that this was yet another fragment of the Codex Sinaiticus? The more we examined it, the more convinced we became that indeed it was. The text is from the first chapter of the book of Joshua, the eleventh verse, in which Joshua commands the children of Israel, ‘Prepare you victuals; for within three days ye shall pass over this Jordan, to go in to possess the land, which the Lord your God giveth you to possess it.’ In every detail, this fragment seemed to match the Codex. But the monastery has other leaves of the Codex Sinaiticus from this same book, which would have been written by the same scribe. 23 When we juxtaposed the letters from these leaves over the image of the newly revealed fragment, the exact correspondence seemed further confirmation of this identification.

It was universal practice in earlier centuries to use parchment fragments in repairing or binding other texts. But now we are presented with the daunting task of wanting to reveal the whole of this fragment, without the risk of damaging it in the process. Experienced conservators will need to discuss the safest way to recover this leaf. It may be that advanced scanning techniques could reveal more of the text, without attempting to remove the fragment for the time being. We should not rule out the possibility of simply leaving the fragment as it is, waiting for technology to develop. This would be better than to act in haste, and risk damaging or losing the text.

Sinai Arabic New Finds 8

24 In the summer of 2006, Hikmat Kachouh, a scholar from Lebanon, came to Sinai to study the Arabic manuscripts of the Gospels. He was taking a doctorate under the supervision of David Parker, at the University of Birmingham. In the course of his studies, he examined over two hundred manuscripts in twenty-one different institutions. Out of them all, this manuscript, Sinai Arabic New Finds 8, was the one that interested him most. On palaeographic grounds, he dated the manuscript to the second half of the eighth century. He concluded that this manuscript follows an archaic Greek manuscript that differed considerably from the Greek Byzantine text. The Western and Alexandrian readings are very many. He writes, ‘No extant Arabic manuscript can claim more textual value than this version.’[7]

But this manuscript remains extremely important for another reason as well. The oldest manuscripts at Sinai are written on parchment. Even after paper reached the Arab world in the tenth century, parchment remained the preferred writing material. Parchment is made from the skins of calf or sheep, in a process that is highly specialized. As a result, parchment has always been expensive, and often difficult to find. But it can be used to produce a book that is beautiful, and that will last for centuries.

If a text written on parchment is no longer wanted, the writing can be rubbed off, and the valuable parchment used a second time. The original writing remains faintly visible beneath the second text. This is what is known as a palimpsest. Because Sinai was so remote, there are many palimpsests: some one hundred and ten manuscripts contain leaves with an underlying text.

25 Very often, it is this original text that is of the greater interest to scholars. If the original writing was large, and if the second text was written at right angles, it is possible with some patience to make out the underlying text. But more often, this is not the case, and the original writing can remain elusive. In the late nineteenth century, it was customary to apply chemicals to the page, to try to enhance the faded ink. A common reagent was hydrosulfurate of ammonia. There were times when this made it easier to read the original script, but one also risked damaging the page, and ruining it.

Recent advances in digital photography techniques promise to make these texts more legible. Pages are photographed using narrow wavelengths of light, ranging from infrared to ultraviolet, in what is called multi-spectral imaging. Photographs taken at specific wavelengths are often combined, and image processing algorithms are applied, the same techniques used to enhance the faint images of stars and galaxies in outer space. Results are not always certain. Also, it is not only technology that is required to recover the texts. It still requires the sharp eyes and long training of experienced scholars to decipher the resulting image.

26 Leading scientists in the field came to Sinai in September of 2009 and took photographs for a pilot project. The results were encouraging, and they have been promised funding for a five year project to photograph manuscripts in their entirety and make them available to scholars. Even the pilot project revealed important discoveries.

Historians have pointed to surprising parallels between earliest Egyptian monasticism, and earliest Irish monasticism. This can be seen in the architecture and the organization of Irish monasticism. We also know that the Irish retained a knowledge of Greek after it had been lost elsewhere in the West. Seven monks from Egypt are said to be buried at Disert Ulidh in Ireland, and the Bibliothèque Nationale possesses an Irish guide for the use of pilgrims to Scetis in Egypt.[8]

27 At Sinai, we only have one Latin manuscript, a Psalter thought to have been written in Jerusalem in the tenth century. But among the New Finds were manuscript leaves written in Latin, in Merovingian and Visigothic hands. One of the most exciting discoveries was an Arabic manuscript that seems to date from the ninth century, making it very early for an Arabic text. The manuscript is itself made up of a patchwork of smaller pieces of parchment, many of which are palimpsests. It contains both classical and Biblical texts in elegant majuscule Greek. It also contains texts in Latin, and one of these hands has been identified as written in an Insular script. This is a term used to classify a style of writing that began in Ireland in the seventh century, and then spread to England, where it flourished between AD 600-850. This was the age of Aidan and Cuthbert and Bede, the time of an unusual flowering of monasticism in England. Now, for the first time, we have manuscript evidence of direct contact between this world and Sinai. This is evidence that their horizon did not stop at Rome. And, can we say? one of the reasons for this flowering would have been their direct contact with the wellsprings of monasticism in Egypt and Sinai.

Camera at St. Catherine's Monastery

The New Digital Camera

28 We have looked at four manuscripts that have been studied recently by scholars, as an indication of the continuing importance of the Sinai library. In each case, digital photographs of these manuscripts proved extremely helpful in their study. The photographs we have seen were made with a system that was acquired some years ago. It consists of a large format camera made by Sinar, with a six megapixel digital back. 29 To take photographs, we use a cradle made in London by Alan Buchanan, which was especially designed for the photography of fragile manuscripts. The manuscript never opens more than 90 degrees. It rests open naturally, and the spine is fully supported, for the cradle turns, from first page to last. As pages are photographed, the platen opposite the camera is incrementally recessed, so that the distance between the camera and the manuscript remains the same. This maintains the focus, and ensures that all of the resulting photographs are uniform in size. Using this camera, we have been able to photograph over one hundred of the Sinai manuscripts. This camera still takes excellent photograph, and will continue to be a useful part of our project.

30 But just last week, we completed the installation of a second camera, that will allow us to expand our project. The installation was made by John Stokes, of Stokes Imaging, in Austin, Texas. The new camera has a 48 megapixel Dalsa CCD. In multi-shot mode, it can capture full colour images in resolutions of up to 192 megapixels. Such photographs are 1.25 gigabytes in size. The new system is not only a great advance in the resolution of the images it can capture. It is also much more efficient.

31 John Stokes licensed the way in which the other cradle supports the manuscripts, and then improved it. 32 The platen opposite the camera moves on a track, which ensures that it is always perpendicular to the camera. 33 It is a simple operation to raise the wedge, turn the page, lower the wedge back into place, and 34 place the new page in position to be phhotographed. 35 The platen is always positioned so that it does not exert any pressure on the manuscript. On our first volume, we were able to average over one page per minute. This allows for the careful handling of the manuscript, and for the time it takes the computer to save each image.

When I return to the monastery in November, I will be bringing with me new lighting systems that employ LED units, with the colour spectrum matched to the CCD. This avoids the fatigue of using flash for extended periods of time.

36 The first manuscript we photographed was an Arabic typikon, giving the order of service, that had been requested by a scholar in Germany. The resulting images were straightened and cropped automatically as a part of the image processing, so that all of the resulting photographs are consistent. They were also automatically saved in three different formats: the full archival image in TIFF format, a derivative in full size, but in a compressed JPEG format, and a small thumbnail image that could be mounted on a web site. 37 We also always photograph the binding of each manuscript. 38 At full resolution, scholars can study many of the details of the binding structure.

39 To test the system at its highest resolution, we photographed a rare illumination of King David that is a part of a Syriac translation of the Book of Kings, dating from the seventh century. 40 The resulting image allows one to see the smallest detail. This is useful not only for the study of the illumination. It is also important as a conservation photograph, allowing one at a future date to check the state of the illumination.

We will continue to meet the requests of scholars as they send us requests. But with the expansion of our digital photography program, we also want to embark on a more systematic photography program. We want especially to photograph all of the Arabic and Syriac manuscripts of the library. We are pleased that there has been a resurgence of interest among scholars in these manuscripts. This would also do much to remind Christians in the Middle East of their own rich heritage.

Saint Catherine’s Monastery is a treasury filled with things new and old. Scholars still have much to learn from its library, its numerous icons, vestments, ecclesiastical vessels, its architecture. In all of this, it is a veritable ark in the wilderness.
