Case File: Heracles vs. Culhwch
Case description: Heracles accuses Culhwch of impersonation. Heracles says he was the first to be forced to do a long list of labors. Culhwch is stealing his thunder, he claims, and getting a lot of press for it, which is unfair.
Case description: Settled. Culhwch asked Heracles if the Greek demigod would like to do his labors instead. Heracles said no and allowed Culhwch to keep working.
