38083 Rhadamanthus           Discovered 1999 Apr. 17 by the Deep Ecliptic Survey.
Rhadamanthus was a son of Zeus and Europa. Because of his just and upright life, after death he was appointed a judge of the dead and the ruler of Elysium, a blissfully beautiful area of the Underworld where those favored by the gods spent their life after death. The name was suggested by E. K. Elliot.
