- c. 1260, Rumi, “5:3500”, in The Masnavi:
  او اگر دیوانه است و فتنه‌کاو، داروی دیوانه باشد کیر گاو.
  u agar divâne ast o fetne-kâv, dâru-ye divâne bâšad kir-e gâv.
  If he is mad and bent on mischief, the cure for a madman is an ox-hide whip.
  (Reynold A. Nicholson translation)
(astronomy) the constellation Taurus
- 1192, Nizami Ganjavi, “Layla and Majnun”, in Khamsa:
  گاو فلکی چو گاو دریا، گوهر بگلو در از ثریا.
  gâv-e falaki čo gâv-e daryâ, gowhar be-galu dorr az sorayyâ.
  the celestial Bull, like the cow of the sea, has on its neck gems, and pearls from the Pleiades.
