Lekos (Lek, Lekas) is the legendary ancestor-eponym of "Legae" tribe of the Caucasus.
[1] In Georgian sources, ethnonym "Leki" (Legae) is usually used to refer to all the peoples of Dagestan.
In Georgian history, during the 18th century, "Leki-anoba" was the name given to sporadic forays by Northeast Caucasian people into Georgia.
Leki were located in the territories of the current residence of the Lezgins, according to one of the leading experts on the history of Caucasian Albania, Kamilla Trever, the legae mentioned next to the gelae apparently lived in the mountainous regions of the Samur River basin.
Louis Vivien, a French geographer of the 19th century, writes that “The Lekzi, also called Lakzi by other Arab authors, are the Legae of the ancient Greeks, the Leki of the Georgians, the Legki of the Armenians, the Lezgi of our travelers; they have not changed either their place of residence or their name”.
