His main contribution to Greek literature is his translation of the Bible into modern Greek, an endeavour that was opposed at that time by ultraconservative circles within the Greek Orthodox Church (cf. the Greek language question). His version was finally allowed in 1924.
He died in Athens on 9 January 1856.
