Detail of one of the early works of Domenikos Theotokopoulos (El Greco), showing the Evangelist Luke painting an icon of the Virgin Hodegetria. The icon of the Virgin Hodegetria was reproduced for the Benaki Museum Shop by the icon-painter Giorgos Bogdanopoulos according to the technique used by Byzantine painters (c. 1560), that is, in egg-tempera combined with earth colours and with polished pure gold leaf.
