Rhadamanthus

Rhadamanthus (1787 – after 1795) was a British Thoroughbred racehorse and sire. In a career that lasted from April 1790 to 1793 he ran nine times and won five races. In the summer of 1790 he proved himself one of the best British colts of his generation, winning The Derby while still undefeated. He raced until the age of six, winning three further races. All of his runs apart from the Derby were at Newmarket. Background Rhadamanthus, described as either a bay or brown horse, was bred by his owner Lord Grosvenor from his mare Flyer, who went on to produce the 1794 Derby winner Daedalus. Rhadamanthus and Daedalus were the most notable horses sired by Lord Grosvenor's horse Justice, who during his racing career had won two races at Newmarket. Racing career 1790: three-year-old season
