He is the compiler of a Greek commentary (scholia) on the Apocalypse, for which he made considerable use of the similar work of his predecessor, Andrew of Caesarea. It was first printed in 1535 as an appendix to the works of Oecumenius. Albert Ehrhard inclines to the opinion that he wrote other scriptural commentaries. To his interest in the earliest Christian literature, caught perhaps from the above-named Andrew, we owe the "Arethas Codex", through which the texts of almost all of the ante-Nicene Greek Christian apologists have, in a great measure, reached us.
