Artaius was an American-bred, Irish-trained Thoroughbred racehorse and sire. In a brief racing career which lasted from the autumn of 1976 until August 1977 he ran seven times and won three races. In 1977 he was one of the leading three-year-old colts in Europe, recording Group One successes in the Eclipse Stakes and Sussex Stakes. He was retired to stud at the end of the season and had limited success as a breeding stallion.
Artaius did not run until the autumn of 1976 when he finished second to Orchestra in the Group TwoBeresford Stakes over one mile at the Curragh. On his first appearance as a three-year-old, Artaius was sent to England to contest the Group Three Classic Trial Stakes over ten furlongs at Sandown Park Racecourse. He started the evens favourite and won comfortably from Night Before. The colt returned to Ireland and was brought back in distance for the Irish 2000 Guineas at the Curragh and finished unplaced behind Pampapaul and The Minstrel. Artaius was then sent to France to contest the Prix du Jockey Club at Chantilly Racecourse where he finished second, half a length behind Crystal Palace. In July Artaius was sent off at odds of 9/2 for the Group One Eclipse Stakes at Sandown Park. He led from the start and won in a race record time of 2:05.30 from Lucky Wednesday and Arctic Tern. A month later Artaius started the 6/4 favourite for the Sussex Stakes at Goodwood where his opponents included the classic winners Nebbiolo and Mrs McArdy. He led from the start again and won easily from Free State with Relkino in third place. At York Racecourse in August, Artaius started odds-on favourite for the sixth running of the Benson and Hedges Gold Cup. In a major upset he was beaten four lengths into second place by Relkino.
Assessment
In 1977, Artaius was given a rating of 129 by the independent Timeform organisation, eight pounds behind his stable companion Alleged.
Stud record
Artaius was retired from racing to become a breeding stallion in Ireland. He was exported to Japan in 1984. He was not a successful sire of winners. The best of his offspring was probably the filly Flame of Tara, who won the Coronation Stakes and produced the outstanding racemare Salsabil and the St James's Palace Stakes winner Marju. In Japan he sired Osumi Roch, who won the Kyoto Daishoten and the Kyoto Kinen in 1992 as well as finishing third in the Takarazuka Kinen. He was also the damsire of the Prix de Diane winner Rafha, who produced the successful sire Invincible Spirit. He was "put out of stud" in Japan in November 1997.
