Goidelic languages
Goídel Glas (Latinised as Gaithelus) is a Gaelic legendary figure and culture hero. According to an Irish and Scottish medieval tradition, Goídel Glas is the creator of the Goidelic languages and the eponymous ancestor of the Gaels. The tradition can be traced to the 11th-century "Lebor Gabála Érenn" ("LGE"). A Scottish variant is due to John of Fordun (d. 1384).
