Euthalius

Euthalius (d. 459) was a deacon of Alexandria and later Bishop of Sulca; he is chiefly known through his work on the New Testament in particular as the author of the "Euthalian Apparatus".

Of Euthalius' activities as a bishop little or nothing is known. Even the location of his episcopal see, Sulca, is a matter of doubt. It can hardly be identified with the see of that name in Sardinia. More likely it was situated somewhere in Egypt, and it has been conjectured by Lorenzo Alessandro Zaccagni that it is the same as Psilka, a city of the Thebaid in the neighbourhood of Syene.
