D. K. (Demetrios Konstantinou) Vyzantios

Born in Constantinople around 1790, Demetrios Konstantinou Vyzantios was a Greek playwright and painter, also known under the name Dimitrios K. Hatziaslanis. Library and bibliographic sources consistently identify him as both a man of the theater and an icon painter, and they place his life between Constantinople and Patras, where he died in 1853.

He is remembered above all for Babylonia (Vavylonia), a comedy first published in 1836 and often noted as one of the early theatrical works of the modern Greek state. The play became especially famous for its humorous treatment of regional speech and miscommunication, turning differences in language into a sharp, memorable piece of social comedy.

Accounts of his later life say that, during the early years of King Otto's reign, he withdrew to Patras, worked as an icon painter, and spent his final years there. Even with a small surviving body of work, his name remains closely tied to the beginnings of modern Greek drama and to one of its most enduring comedies.
