Bahamut

Bahamut or Bahamot (/bəˈhɑːmuːt/ bə-HAH-moot; Arabic: بهموت‎‎ Bahamūt, from Hebrew בְּהֵמוֹת "Behemoth") is a large fish that supports the earth in Arabian mythology. In some sources, Bahamut is described as having a head resembling a hippopotamus or elephant.

In Arabic mythology, Bahamut is a giant fish acting as one of the layers that supports the earth. In Jorge Luis Borges' Book of Imaginary Beings, Bahamut is "altered and magnified" from Behemoth and described as so immense that a human cannot bear its sight; "[all] the seas of the world, placed in one of the fish's nostrils, would be like a mustard seed laid in the desert."

Edward William Lane cites two cosmological accounts from Ibn al-Wardi (d. 1348) that feature Bahamut. One account describes Bahamut as a fish floating in water, supported by darkness. On the fish is a bull called Kujata, on the bull, a ruby mountain; on the mountain, an angel; the angel holds and supports the seven earths. In another account, Bahamut supports a bed of sand, on which stands a bull, on whose back rests a rock which holds the waters in which the earth is located. Beneath the fish are layers of suffocating wind, a veil of darkness, and mist. Other sources describe Behemoth as a layer in similar conceptions of Arabic cosmography.

According to Argentine writer Jorge Luis Borges, Bahamut is the giant fish that Jesus beholds in the 496th night of the One Thousand and One Nights. Bahamut in this telling is a giant fish swimming in a vast ocean. It carries a bull on its head; the bull bears a rock, and above the rock is an angel who carries the seven stages of the earths. Beneath Bahamut is an abyss of air, then fire, and beneath that a giant serpent called Falak.
