5797 Bivoj           Discovered 1980 Jan. 13 by A. Mrkos at Klet.
This Amor-type object is named for the honorable hero of ancient Bohemian myths, known for his great courage and other good qualities. Bivoj conquered a colossal wild boar barehanded to save the crops and lives of his people. He later became acquainted with and married Kazi, the oldest daughter of prince Krok. Name suggested by J. Ticha, M. Tichy and Z. Moravec.
