Narrative

Trophonius and Agamedes, sons of Erginus (or of Apollo in some reports), were famed builders. For Hyrieus of Hyria they constructed a treasury with one stone so fitted that they could remove it and steal from the store. Hyrieus set a trap; Agamedes was caught. Trophonius cut off his brother’s head so that the body could not be recognized, then fled; the earth opened and received him at Lebadeia, where he became the oracular hero. A different tradition says the brothers built Apollo’s first temple at Delphi and, granted a boon, died peacefully in sleep after six days—Zeus’s gift of the best end for mortals. Catalogue the treasury betrayal as the dark Boeotian crime-story that explains Trophonius’s chthonic disappearance, apart from the serene Delphic death variant and apart from the later oracle ritual.
