 In 1563, at the age of twenty-two, El Greco was described in a document as a "master" ("maestro Domenigo"), meaning he was already an enrolled master of the local guild, presumably in charge of his own workshop.He left for Venice a few years later, and never returned to Crete.His "Dormition of the Virgin", of before 1567 in tempera and gold on panel (61,4 x 45 cm, Holy Cathedral of the Dormition of the Virgin, Hermoupolis, Syros) was probably created near the end of El Greco's Cretan period.
