Two very early manuscripts exist of a Syriac translation of the “Church History” of Eusebius. One of these dates from 462 A.D. It was bought from the monks of the Nitrian desert in Egypt, and destined for the British Library; but the middleman, a certain Pacho, double-crossed his masters and instead sold it, together with three other books, to the Tsar for 2,500 roubles – a significant sum in those days. Today it has the shelfmark, National Library of Russia, New Syriac mss. 1.
The Syriac version was first published in 1897 as Histoire ecclésiastique d’Eusèbe de Césarée; éditée pour la première fois par Paul Bedjan. It is a curious fact that I have been quite unable to locate this book online. A couple of years later another edition was made.
Can anyone point me to the Bedjan edition?
UPDATE: Adam McCollum points me to a copy online here. If you page down, you will find a download link at the right.
