The fact that sovereignty is related to generosity contributes to one of the most powerful themes of Celtic wisdom: the importance of hospitality as a social virtue. Hospitality is basically the generosity shown to strangers and guests in our midst. Mythology abounds with stories that suggest a king rules well when his court is filled with hospitality — that a visitor must eat till satisfied before even beginning to discuss whatever business brought him to the royal hall. By contrast, kings who do not practice hospitality are satirized, the land goes barren under their rule, and ultimately they are forced to abandon the throne.

Carl McColman, 366 Celt
