Esus, Hesus, or Aisus was a Gaulish god known from two monumental statues and a line in Lucan’s Bellum civile. The two sculptures where Esus appears are the Pillar of the Boatmen from among the Parisii, on which Esus is identified by name and a pillar from Trier among the Treveri with similar iconography. In both of these, Esus is portrayed cutting branches from trees with his axe. Esus is accompanied, on different panels of the Pillar of the Boatmen, by Tarvos Trigaranus the ‘bull with three cranes’ Jupiter, Vulcan, and other gods. A well-known section in Lucan’s Bellum civile (61 to 65 CE) refers to gory sacrifices offered to a triad of Celtic deities Teutates, Hesus (an aspirated form of Esus), and Taranis. Variant spellings, or readings, of the name Esus in the manuscripts of Lucan include Hesus, Aesus, and Haesus. Among a pair of later commentators on Lucan’s work, one identifies Teutates with Mercury and Esus with Mars, watch video for more ancient mystery on Youtube.
