holy Scriptures, which he had ordered me to prepare for him." Athanasius could have received this request between 337 and 339. Codex Sinaiticus and Vaticanus Constantin von Tischendorf, discoverer of Codex Sinaiticus, believed that Sinaiticus and Vaticanus were among these fifty Bibles prepared by Eusebius in Caesarea. According to him, they were written with three (as Vaticanus) or four columns per page (as Sinaiticus). Tischendorf's view was supported by Pierre Batiffol. Frederick Henry Ambrose Scrivener rejected Tischendorf's speculation because of differences between the two manuscripts. In Sinaiticus, the text of the Gospels is divided according to the Ammonian Sections with references to the Eusebian Canons, but Vaticanus used the older system of division. Vaticanus was prepared in a format of 5 folios in one quire, but Sinaiticus had 8 folios. According to Scrivener, Eusebian Bibles contained three or four folios per quire (Scrivener used a Latin version of Valesius). Scrivener stated that the Eusebian is unclear and should not be used for a doubtful theory. Westcott and Hort argued the order of biblical books on the Eusebian list of the canonical books, quoted by Eusebius in "Ecclesiastical History" (III, 25), is different from every surviving manuscript. Probably none of the 50 copies survive today. Caspar René Gregory believed that Vaticanus and Sinaiticus were written in Caesarea, and they could belong to the Eusebian fifty. According to Victor Gardthausen Sinaiticus is younger than Vaticanus by at least 50 years. Kirsopp Lake states "copies of three and four columns" is grammatically sound, but there appears not to be good evidence for this technical use of the words. "Sending them by threes of fours" is the most attractive, but there is no evidence that τρισσα can denote "three at a time". Regarding "in three or four columns per page," there is only one known manuscript written in that way – Sinaiticus. Sinaiticus has a curious spelling of the word κραβαττος as κραβακτος; Sinaiticus spells Ισραηλειτης as Ισδραηλειτης, Vaticanus as Ιστραηλειτης; these forms have been regarded as Latin, and they can be found in papyri from Egypt. There is no other known Greek district in which these forms were used. The argument for a Caesarean origin of these two manuscripts is much weaker than Egyptian. According to Heinrich Schumacher, Eusebius instead prepared fifty lectionaries, not Bibles. Skeat argued that Sinaiticus was a first attempt to produce a full Bible in fulfillment of Constantine's order
