Barsils / Barsilts, Chinese Baysi, were a semi-nomadic Eurasian tribe of Turkic linguistic affiliation, and possibly identical with the Bagrasik. Barsils are first mentioned in the Chinese annals as the 15th of the 15 TurkicTele tribes. The Chinese records about the Western Turkic Kaganate ca. 630 mention a Khan of the Bars (Tr. leopard) tribe, a member of five "Nushibi" (Ch. 弩失畢) on-shadapyt right wing tribes, under a name of Tun-ashpa [ra]-erkin. Barsils are included in the list of steppe people living north of Derbend in the Late Antique Syrian compilation of Zacharias Rhetor, and are also mentioned in documents from the second half of the 6th century AD in connection with the westward migration of the Eurasian Avars. When the Avars arrived, according to Theophylact Simocatta, "the Barsilt (Barsilians), Onogurs, and Sabirs were struck with horror (...) and honoured the new-comers with brilliant gifts."

In an Armenian geography of the 7th century, the Barsils are described as living on an island, distinct from the Bulgars and Khazars and at odds with both nations. In addition, it describes them as possessing large flocks of sheep, supporting the notion that they were at least partly nomadic. Mikhail Artamonov theorized that "Barsilia" was located in northern Daghestan, but subsequent scholars have disputed this theory, as the sedentary local population of the relevant period and region appears to have been, for the most part, settled in permanent fortress-towns.

Danyel Gérard (born Gérard Daniel Kherlakian, 7 March 1939, Paris) is a French pop singer and composer.

Gérard was born in Paris to an Armenian father and an Italian mother, but grew up mainly in Rio de Janeiro. In 1953 he returned again to Paris and became a choir boy at Notre Dame. Following this he played in the rock and roll band The Dangers. In 1958 he made his first recordings: "Viens" (a cover of the Kalin Twins' hit "When") and "D'où reviens-tu Billy Boy" (adapted from Dorothy Collins' "Where Have You Been, Billy Boy"), making one of the first young French singers to successfully sing rock and roll (his only rivals at this stage were Richard Anthony, Claude Piron (later better known as Danny Boy) and Gabriel Dalar), although his commercial impact was very limited; despite a latter-day, revisionist recasting of him as the French Elvis Presley, he was nevertheless one of France's first rock stars. After cutting a further EP featuring a cover of Don Gibson's "Oh Lonesome Me" ("O pauvre moi") which was buried by a rival version by Sacha Distel and an adaptation of the Fraternity Brothers' "Passion Flower" ("Tout l'amour"), we was drafted and spent from 1959 to 1961 he was a soldier in North Africa. Subsequently he was a singer and guitarist in various bistros. On his return, he resumed his singing career with the minor 1961 hit "Oh Marie-Line" but by then he had been overtaken by newer singers such as Johnny Hallyday. He also began to write songs, penning tunes for Johnny Hallyday, Sylvie Vartan, Dalida, Richard Anthony, German-based star Caterina Valente, actress Marie Laforêt and Austrian singer Udo Jürgens.
