the dioceses of Cerasous and Rizaion were abolished. The diocese of Rizaion and the bishopric of Of were abolished at the time due to the Islamisation of the Lazs. Most of them subsequently converted to Sunni Islam. There are several ruined churches in present-day Rize and Artvin districts, such as; Jibistasi in Ardeşen, Makriali (Noghedi) in Hopa, Pironity in Arhavi etc. There are also a few Christian Laz in the Adjara region of Georgia who have reconverted to Christianity. Mythology Famous for its saga and myths and bounded by the Black Sea and the Caucasian Mountains, the ancient region of Colchis spreads out from West Georgia to Northeast Turkey. The famous tale in Greek mythology of the Golden Fleece in which Jason and the Argonauts stole the Golden Fleece from King Aeetes, with the help of his daughter Medea, has brought Colchis into the history books. Festival Kolkhoba is an ancient Laz festival. It is held at the end of August or at the beginning of September in Sarpi village, Khelvachauri District. Festival has revived the former lifestyle of Lazeti residents and moments of human relations typical to the times of ancient Greece and Colchis related to the Argonauts journey to Colchis. During the celebration of Kolkhoba theater performances are followed by a variety of activities and it is considered one of the main public festivals.

Koyuncu, who died of cancer in 2005, was also an activist for the Laz people and has become a cultural hero.

These may be solemn and precise, performed by lines of men, with carefully executed footwork, or extremely vigorous with the men dancing erect with hands linked, making short rapid movements with their feet, punctuated by dropping to a crouch. The women's dances are graceful but more swift in movement than those encountered in Georgia. In Greece such dances are still associated with the Pontic Greeks who emigrated
