7695 Premysl           Discovered 1984 Nov. 27 by A. Mrkos at Klet.
Named for a mythical hero Premysl, called Ploughman. He married princess Libuse, and they became the mythical founders of the royal dynasty of the Premyslids, ruling over Bohemia until 1306. Bohemian kings Premysl Otakar I (?-1230) and Premysl Otakar II (?-1278) are considered the most reputable members of this dynasty. Name suggested by J. Ticha, M. Tichy and Z. Moravec.
