Severus Sebokht of Nisibis flourished in the early-mid 7th century and was bishop of the great convent of Kenneshrin (the "Eagle's nest") at which Greek was studied extensively. He was one of the foremost scientific writers of his time. His works are mainly scientific or philosophical in character, although little has been translated into English.
He is best known today for a remark which shows that what we call today "Arabic" numerals were coming into use.

Material from Nau, Le traite, ROC 1929
Severus Sebokht is mainly known as a populariser of Greek philosophy among the Syrians . But thanks to a manuscript brought to France by Addai Scher, we now know that he also played an important role in the transmission of Greek science. The manuscript, now Paris, Syriaque 346, dated 1309 AD, contains his correspondence, in the last years of his life, only with an otherwise unknown Basil, a priest in Cyprus, so if we may conclude that he wrote 27 chapters over a number of years to a single correspondant, his scientific activity must have been considerable.
The first 18 chapters (folios 78-121v) form a distinct treatise with an incipit and explicit. Severus refers to it in a later writing in the same manuscript.
The first 5 chapters are directed against astrologers. These attributed to the constellations effects on earth which were in line with their names. Severus shows at length that these names are arbitrary, purely conventional, and so have no connection with the real nature of the stars. Chapter 4 contains long quotations from Aratus which are mostly missing in our Greek texts of the Phenomena of this author. Chapter 5 contains an interesting selection of Syriac technical astrological jargon, used previously by Bardesanes in his Book of the laws of the countries and also the Syriac names of the constellations and principal stars, in use throughout the treatise. The Syriac text of these chapters was published by Nau because of its use to Syriac scholars.
Severus then goes on to give a cosmography, which must have been very much in fashion at the time, since it was the basis of astrology. He lists the number of constellation, their names, remarkable stars, when these rise and set, the signs of the zodiac, the milky way, etc.
Two short extracts of chapters 17 and 18 have already been published by Sachau (Inedita Syriaca, Vienna (1870), pp.127-134) from BL. Add. 14538, a ms. of the 10th century.

Severus Sebokht (d. 666-7 A.D.) 1 of Nisibis 2, bishop of the convent of Ken-neshre, at this time one of the chief seats of Greek learning in western Syria 3 flourished at the same time as Marutha, under the patriarch Athanasius Gammala (died in 631 4) and his successor John.
He devoted himself to philosophical and mathematical as well as theological studies 5. Of the first we have specimens in his treatise on the syllogisms in the Analytica Priora of Aristotle, his commentary on the Περι ερμηνείας, and his letters to the priest Aitilaha of Mosul on certain terms in the Περι ερμηνείας, and to the periodeutes Yaunan or Jonas on some points in the logic of Aristotle 6. Of his astronomical and geographical studies there are a few examples in Brit. Mus. Add. 14538, ff. 153-155 7, such as whether the heaven surrounds the earth in the form of a wheel or sphere, on the habitable and uninhabitable portions of the earth, on the measurement of the heaven and the earth and the space between them, and on the motions of the sun and moon 8. In the Royal Library at Berlin there is a short treatise of his on the astrolabe 9.
More or less theological in their nature are his letter to the priest and periodeutes Basil of Cyprus, on the 14th of Nisan, A. Gr. 976 (665 A.D.) 10, a treatise on the weeks of Daniel 11, and letters to Sergius, abbot of Shiggar (Sinjar), on two discourses of Gregory Nazianzen 12. He is also said to have drawn up a liturgy 13.

Material from Sebastian Brock
Severus Sebokht (W; d.666-7). Bishop of the monastery of Qenneshre, and one of the most learned men of his time in the fields of astronomy and philosophy. Several works of his in both these fields survive, notably treatises on the Astrolabe and on the Constellations, letters on points of logic addressed to Aitalaha of Nineveh and to a periodeutes Yaunan, and a treatise on Syllogisms (written in 638). He also translated from Middle Persian a compendium on logic written by Paul the Persian for the Persian shah Khosro I (d. 579).

There are some MSS I know of:
1. There is a MS of his treatise on Aristotle's Analytica Priora in Mingana MS Syr 44 part G which is preceded by the same work of Aristotle in Syriac translation. See Mingana's catalogue, volume 1 column 114. This West Syrian MS is dated AD 1575 and it was written in Deir Zafaran, (The Saffron Monastery).

Nau, in the article I mentioned, is interested in astronomical data, and he quotes from that ms. a letter by Severus to a Cypriote priest named Basil from AD 662, in which he refers to Bardaisan’s computations of planetary conjunctions, the section on Arabic numbers. The same ms. apparently also had Severus’ treatise on the latitude of climata, and perhaps the one on the astrolabe. The latter is ed. Nau, Journal Asiatique, 9th series, vol. 13, 1899. I am not sure what the ms. is for this one, though.

For an overview of the broader cultural context for the transmission of Aristotelian logic and Greek medicine into Syriac during the sixth century, you might want to read the third chapter of my new book, The Legend of Mar Qardagh: Narrative and Christian Heroism in Late Antique Iraq (UC Press, 2006). Sergius of Resh Aina holds a key place in my argument.
If you haven't done so already, you should also check the entries under Severus Sebokht and philosophy in Syriac Studies. A Classified Bibliography (1960-1990) (Kashlik, Lebanon, 1996). I thhink there are some later supplements published in Parole de l'Orient, and after that, in Hugoye.

He wrote letters on theological subjects to Basil of Cyprus and Sergius, abbot of Skiggar, as well as two discourses on St. Gregory Nazianzen. On Aristotelian logic he composed a treatise on the syllogisms in the Analytics of Aristotle, a commentary on the Hermeneutics which was based on the commentary of Paul the Persian, a letter to Aitilaha of Mosul on certain terms used in the Hermeneutics (Brit. Mus. Add. 17156), and a letter to the periodeutes Yaunan on the logic of Aristotle (Camb. Univ. Lib. Add. 2812).
In addition to these works on logic he also wrote on astronomical subjects (Brit. Mus. Add. 14538), and composed a treatise on the astronomical instrument known as the astrolabe, which has been edited and published by F. Nau (Paris, 1899). In all this he showed himself the product of Alexandrian science and illustrated the widening scientific interests of the period. It seems that he took steps towards introducing the Indian numerals, but this was not carried on by any immediate successor. His work represents the highest level reached by any Syriac scientist and this, it will be noted, was associated with Kennesrin.
In 662AD he wrote concerning the new numerals, which were moving West and were to become what we know as 'Arabic' numerals:
- I will omit all discussion of the science of the Indians, ... , of their subtle discoveries in astronomy, discoveries that are more ingenious than those of the Greeks and the Babylonians, and of their valuable methods of calculation which surpass description. I wish only to say that this computation is done by means of nine signs. If those who believe, because they speak Greek, that they have arrived at the limits of science, would read the Indian texts, they would be convinced, even if a little late in the day, that there are others who know something of value. (Found online: supposed to come from "The Wonder That Was India, A Survey of the Culture of the Indian Sub-Continent Before the Coming of the Muslims", by A.L. Basham, Reader in the History of India in the University of London, Sidgwick and Jackson, London, 1954, repr. 1961).
According to google book search's scan of page 48 of A History of Mathematical Notations, by Florian Cajori (1993):
- The earliest-known reference to Hindu numerals outside of India is the one due to Bishop Severus Sebokht of Nisibus, who, living in the convent of Kenneshre on the Euphrates, refers to them in a fragment of a manuscript (MS Syriac [Paris], No. 346) of the year 662 A.D.
- Like many of his contemporaries, Severus was bicultural, partaking of the Byzantine Greek influence on Western Syrian intellectual circles while fully immersed in his own Syrian cultural milieu. He does, however, criticize the contemporary Greek tendency to assume intellectual superiority and asserts his own capabilities as a native Syrian, raising a strong polemical voice against the cultural hegemony of the Greek-speaking world over that of provincials. A leading figure in the teaching and commentary tradition of Aristotelian philosophy, especially in logic and syllogisms, Severus produced a Discourse on Syllogisms in Prior Analytics (638 CE) and wrote commentaries on other philosophical texts. He translated into Syriac Paul the Persian's commentary on Aristotle's De interpretatione ... He was familiar with Ptolemy's Handy Tables, and there is some indication that he translated the Almagest into Syriac; in any case, he most certainly taught it in the school of Nisbis and then later in Western Syria ...
- Specialized treatments of Severus and his contemporaries appear in S. Brock, "From Antagonism to Assimilation: Syriac Attitudes to Greek Learning" in Syriac Perspectives on Late Antiquity (London: 1984): V, 17-34, esp. 23-4, 28 and in two works by D. Pingree: "The Greek Influence on Early Islamic Mathematical Astronomy," Journal of the American Oriental Society 93 1993: 32-43, esp. 34-5; and "The Teaching of the Almagest in Late Antiquity" in The Sciences in Greco-Roman Society. ed. T. Barnes. (Edmonton: 1994): 73-98, esp. 94-5.
From google book search, in "Aristotelian Meteorology in Syriac: Barhebraeus, Butyrum Sapientiae, Books of Mineralogy ..." By Hidemi Takahashi, p. 325, it states that Severus was familiar with Ptolemy's Handy Tables (see the French translation of "On the Constellations" by Nau , p.240; Nau [1930-1], p.343 (index)), as was Sergius of Reshaina (Sachau  225.17).
The following manuscripts contain works by Severus Sebokht.
Ms. Paris Syriaque 346
This manuscript contains a large quantity of works by Severus Sebokht, and is the main source for his works. 
The Syriac manuscripts 1-288 are described by Herman Zotenberg in his Catalogue des manuscrits syriaques et sabéens (mandaïtes) de la bibliothèque nationale, Paris (1874), which was completed for mss. 289-334 by J-B. Chabot. The following manuscripts are described in a handwritten supplement to Chabot's catalogue, which can only be consulted in the "Salle Orientale" (Oriental reading room) at the Bibliotheque Nationale.
Ms. Syr. 346 has a relatively detailed description at the head of the volume, probably by Chabot, on the first guard-leaf. It contains 177 f. The first 36 folios are missing. It is written in a fine Serto hand. Each page has 28 lines, and is 160 x 120 mm.
It contains a collection of various treatises on astronomy, most of them by Severus Sebokht of Nisibis. Here is a list of contents. (The attributions are elderly and perhaps need revisiting).
- ff. 1-36 : Ptolemy. Megale suntaxis in Syriac. Unpublished.
- f. 36v-51v : Severus Sebokht of Nisibis. Treatise on the figures of the astrolabe. This text was edited by the abbé François Nau, Paris 1899 (available at the BNF Richelieu, manuscrits orientaux, imprimé 8° imp or 116 (9.13)).
- ff. 51v-77v. Severus Sebokht of Nisibis. Treatise on the causes of solar and lunar eclipses, winds and other natural phenomena.
- f. 78r-121v. Severus Sebokht of Nisibis. The figures of the zodiac. According to the author of the catalogue notice, only the last chapter is known and may be found in a Syriac ms in the British Library, Mss Add. 14538, published by Eduard Sachau in Inedita Syriaca, Wien (1870), pp. 127-134.
- ff. 122-145. Severus Sebokht of Nisibis. The reunion of the seven planets, how to predict an eclipse of the sun, the seven climates of the earth and how to measure them, the division of heaven into 5 zodiacs, and two chapters : one is devoted to the 14th month ("consacree au 14e lune"), the other to the cycle of 95 years and the birth of Christ. They were copied at the request of Basil of Cyprus.
- ff. 145r-161r. Giwargi (Georges, bishop of the Arab tribes) : the birth of the year, the movement of the stars, and the influence of the moon and a corresponance with John the Stylite, published by Viktor Ryssel (Georgs, des Araberbischofs, Gedichte und Briefe... Leipzig, 1891).

- ff. 172-177v : Severus Sebokht of Nisibis. Treatise on Astronomy.
- Colophon on f. 168v : Finished in 1309 at the monastery of Mar Hanania, Mardin.
The very brief notice in the catalogue mentions the existence of 13 ff. detached from this manuscript and forming ms. Syriac 392. Laurent Héricher adds that apparently only the first 8 folios can be from ms. Syriaque 346. The folios are very damaged and practically illegible. They have been folded in half.
The manuscript was brought to France by Addai Scher. 
British Library Ms. Additional 14538
This manuscripy contains "Treatises against heresies, and other theological works; very imperfect. On vellum, of the XIth or XIIth century. Quarto." 
The works of Severus Sabocht occupy folios 153b- 155a.
- 1.On the length of the day and night;
- 2.whether the heaven surrounds the earth;
- 3.habitable and uninhabitable portions of the earth;
- 4.on the measurement of the heaven and earth;
- 5.motion of the sun and moon.
These are the texts attributed to Severus, which were edited and published by Sachau in Inedita Syriaca.
More information is apparently available in W. Wright, Catalogue of Syriac manuscripts in the British Museum, London (1871). A full description of Add.14,538 is available in vol.II, pp.1003-1008.  But this I have not seen.
Berlin Ms. Petermann I 26 (once Ms. 186 in the Sachau catalogue)
Manuscript Petermann I 26 (Catalogue Sachau 186) contains various works by Severus Sebokht. The treatise on the astrolabe is contained on folios 82b-98a. For details you should refer to the catalogue by Sachau, volume 2, published in 1899. 
Alqosh, Monastery of Rabban Hormizd (Notre-Dame des Semences), Ms. 50
The catalogue with brief descriptions of this library as it was in 1906 is available online,  and gives the following details.
Codex 50 has the title "Book of the Isagogue, Analytics and Categories". This contains (the first 4 are also in codex 49, which has the same title):
- The Isagogue of Porphyry, as translated by Probus, priest, archdeacon and archiater of Antioch.
- The Dialectic of Aristotle.
- The treatise of Sarguis, archiater, on the use of the Categories of Aristotle.
- The peri hermenias of Aristotle, translated from Greek to Syriac by Probus again, with a commentary by Probus.
- The abbreviated commentary on the peri hermenias, composed by Paul the Persian and translated from Persian into Syriac by Severus Sebokht.
- A letter by Severus Sebokht on the logic of Aristotle, addressed to a Yaunan, visitor.
The manuscript is undated. Whether this ms. still exists is unknown.
