The Vates: Gaul's Diviners and Sacrificers

Ancient descriptions of the vates focus overwhelmingly on divination and sacrifice rather than on the broader priestly and judicial authority Caesar attributes to druids proper, or the poetic and genealogical function attributed to bards. Strabo, drawing on now-lost earlier Greek ethnographic writing about Gaul, describes vates as interpreters of nature and performers of sacrifice who were consulted specifically for prophecy, while other classical sources describe augury from the flight of birds, the reading of sacrificial victims, and other omen-based techniques as belonging to this class rather than to druids generally, though the sources are not always careful to keep the three Gaulish classes as distinct from one another as a modern reader might like.

The vates class receives considerably less surviving classical description than druids do, and next to nothing in the way of a named individual vates comparable to the handful of named druids classical authors do mention, which makes reconstructing the vates' precise ancient role harder than reconstructing the bard's or the druid's; modern Druidry's Ovate grade is therefore built on a thinner classical foundation than the other two grades, filled out considerably by later scholarly speculation about Celtic divinatory practice and by comparison with druidic-adjacent seer figures in early medieval Irish and Welsh literature, whose own relationship to the continental vates remains debated rather than settled.
