Tarvos Trigaranus or Taruos Trigaranos[1] is a divine figure who appears on a relief panel of the Pillar of the Boatmen as a bull with three cranes perched on his back.

[2] In the Gaulish language, taruos means "bull,"[3] found in Old Irish as tarb (/tarβ/), in Modern Irish/Gaelic as tarbh and in Welsh as tarw (compare "bull" in other Indo-European languages such as Latin taurus from Greek "ταύρος" or Lithuanian taŭras).

[5] A pillar from Trier shows a man with an axe cutting down a tree in which sit three birds and a bull's head.

The juxtaposition of images has been compared to the Tarvos Trigaranus and Esus panels on the Boatmen monument.

[6] It is possible that statues of a bull with three horns, such as the one from Autun (Burgundy, France, anciently Augustodunum) are related to this deity.
