In his first book against Rufinus, Claudian places Odysseus’ meeting with the shades of the dead in Gaul–or, rather, shows that he is familiar with a tradition that places the event there (fertur):
Est locus extremum pandit qua Gallia litus
Oceani praetentus aquis, ubi fertur Ulixes
sanguine libato populum movisse silentem. (In Rufinum 1.123-5)
Does anyone know the antecedent for this tradition locating the event, not just at the edge of the world, but precisely in Gaul? I don’t recall coming across this before, but that presumably just shows my ignorance. Is this found anywhere in the mythographical tradition?
