Godolphin Arabian
Sir Visto's sire was the undefeated Irish champion Barcaldine, a representative of the Godolphin Arabian sire line, who also sired the double Classic winner Mimi. Sir Visto’s dam, Vista, was an excellent broodmare who also produced the Derby runner up Velasquez, and Bona Vista the 2000 Guineas winner who, as the grandsire of Phalaris is the male-line ancestor of most modern thoroughbreds.
