He is probaly identical with Oliverъ from Prilep, who was the scribe of the Menaion for July and August, which has been preserved in the collection of manuscripts at the Dečani Monastery (Nr. 32). Mentioned in the fragmentary written entry. The record appears in the Festal Menaion for the Months September-December (Nr. 913), which is kept in the National library of Serbia. He was probably the Kefalija in the region of Pelagonia during the reign of Markos (Marko Kraljević). This hypothesis is based on two other fragmentary preserved written records in the same manuscript (ōt kefalie ōlivera gnь /snь/…mitropolitu pelagoniskamu [ōt] … gospodinu mi kralju Marku).
