Out of the hundreds of worthy poets that flourished in modem Greece, Ritsos is one of the outstanding few, on a level with Cavafy, Seferis and Elytis. The poet of Romiosini, Epitaphios and Lianotragouda is well-known by every Greek, especially since his unique poetry was set to music by Mikis Theodorakis."
