Ash or Yuc (Tamazight: ⵢⵓⵛ, <small>romanized:</small> Yuc, IPA: [jʊʃ]) was an Amazigh sky god worshipped by the Libyan and Tehenu tribes of the Western Desert, an area of desert that lies west of the Nile River. He was regarded as the "Lord of the Tehenu" by the Ancient Egyptians.
In particular, he was identified by the ancient Egyptians as the god of the vineyards of the western Nile Delta
Some depictions of Ash show him as having multiple heads, unlike other Egyptian deities, although some compound depictions were occasionally shown connecting gods to Min. In an article in the journal Ancient Egypt (in 1923), and again in an appendix to her book, The Splendor that was Egypt, Margaret Murray expands on such depictions, and draws a parallel to a Scythian deity, who is referenced in Sebastian Münster's Cosmographia universalis.
The idea of Ash as an import god is contested, as he may have been the god of the city of Nebut, now known as Naqada, before Set's introduction there. One of his titles is "Nebuty" or "He of Nebut", indicating this position.
