In the central part of the lower register is the titular of the polyptych, St. Martin, flanked by patron saints of Zadar, St. Anastasia and St. Simeon.

According to records from 1746, during visitation by the archbishop Mate Karaman, it can be assumed that a painting of the Blessed Virgin Mary was once in the uppermost register, but it has since been lost.

Ornamental frame, originally connecting polyptych paintings, was created by a local master Ivan of Korčula.

The figures are painted on a background with rocky hills, with no unitary treatment of the landscape based on geometric perspective but, as in Gentile Bellini's works, with a series of separate blocks.

The paintings were damaged during World War Two when they were moved from a humid shelter to a dry attic.
