The Italo-Byzantine style of his first paintings evolved under the influence of more refined works by Cretan school and Venetian artists.

In his maturity, Apakas showed stylistic affinities with Michael Damaskinos, Georgios Klontzas, Victor of Crete and Leos and Elias Moskos.

Ten of his paintings have survived, and are featured in public foundations, private collections, churches and monasteries, mostly in Greece.

His most notable work is Ignatius of Antioch, whose lions were emulated by many subsequent Cretan School artists.

Another common theme between Apakas, Theodore Poulakis and Elias Moskos was the Tree of Jesse.
