The Thyestes Chase is a National Hunt handicap steeplechase run in Ireland.
Thyestes, by The Tetrarch (out of Tetratema), was bred by Major Victor McCalmont of Mount Juliet and trained by Atty Persse at Stockbridge, Wiltshire.
The Thyestes trophy was presented to the Kilkenny Show by Major Dermot McCalmont for a 5-year-old likely to make a good hunter.
The trophy was won by a horse owned by Mr John McEnery of Rossenarra Stud, Kells, County Kilkenny and ridden by his son Martin.
The McEnery family then presented it to Gowran Park for the first running of the Thyestes Chase in 1954.
