Kellis Greek-American ninety-two years old, with his synonymous Yiannis G. Kellis, his first joy from the nine. The Grandson with his Professors, the Linguists at the Ohio State University USA, propelled the grandfather to speed up the publishing of his book “Mesta, People of Mesta, Legends of Mesta”. A monumental work of love for his Mesta, the castle village of the Greek mastic-producing island of Chios. Here he awakens to rescue the dormant Mesta language, the unique ancestral one. He records in sound the unwritten sayings, and the traditions of the pre-Christian, Medieval, post-Byzantine, and modern times. Written in his own language (1850), translated into the dialect of 1950, and now into English. The Reader will be taught by the life of Grandfather and Grandmother.
