The river was regarded as a god by the ancient Greeks, as were most mountains and streams; the poet Nonnus in the Dionysiaca (section 26, line 350) makes the Hydaspes a titan-descended god, the son of the sea-god Thaumas and the cloud-goddess Elektra. He was the brother of Iris, the goddess of the rainbow, and half-brother to the Harpies, the snatching winds. Since the river is in a country foreign to the ancient Greeks, it is not clear whether they named the river after the god, or whether the god Hydaspes was named after the river. Alexander the Great and his army crossed the Jhelum in BC 326 at the Battle of the Hydaspes River where it is believed that he defeated the Indian king, Porus. According to Arrian (Anabasis, 29), he built a city "on the spot whence he started to cross the river Hydaspes", which he named Bukephala (or Bucephala) to honour his famous horse Bukephalus or Bucephalus which was buried in Jalalpur Sharif. It is thought that ancient Bukephala was near the site of modern Jhelum City. According to a historian of Gujrat district, Mansoor Behzad Butt, Bukephalus was buried in Jalalpur Sharif, but the people of Mandi Bahauddin, a district close to Jehlum, believed that their tehsil Phalia was named after Bucephalus, Alexander's dead horse. They say that the name Phalia was the distortion of the word Bucephala. The waters of the Jhelum are allocated to Pakistan under the terms of the Indus Waters Treaty. India is working on a hydropower project on a tributary of Jhelum river to establish first-use rights on the river water over Pakistan as per the Indus waters Treaty.[5]
