As in other cultures of antiquity, sacrifices were an essential element of religious practice among the Celts. The texts mention in particular the practice of human sacrifices, clearly attested by a certain number of discoveries. The poet Lucain evokes “those who appease with dreadful blood the cruel Teutates and the horrible Esus at the savage altars and Taranis, an altar no less cruel than that of the Scythian Diana”. A commentator of Lucan (Scholies of Bern) left us some precisions as for the nature of the human sacrifices devoted to these gods the victims intended for Taranis were immolated by fire, those intended for Teutates drowned in a tank, finally, those intended for Esus, hanging from a tree and flayed.
