Osh

The name of the city of Osh derives from the river Vakhsh, anthropomorphised there as a water goddess of the same name, who was worshipped (in tandem with Atar, sacred fire) in a Zoroastrian shrine or fire temple situated in the Eagle Cave in the ancient sacred mountain Sulaiman-Too. The river Vakhsh itself, known also as Surkhob or Kyzyl-Suu ( Turkic: "red water") is a tributary of the Amu Darya, the course of the Vakhsh lying outside and to the South of the Fergana valley, rising as it does on the west side of the 3,536m Taunmurun pass (east of the village of Sary-Tash) and flowing southwest to its confluence with the Panj at Takht-i Sangin to form the Amu Darya. Oxus, the ancient name of the Amu Darya, like Osh, is cognate with the river name Vakhsh, revealing that the present day Vakhsh/Kyzyl-Suu was conceived to form the upper reaches of the river now known as the Amu Darya. …
