Spilletta was a bay filly bred by the Sir Robert Eden and foaled in 1749. She was sired by the undefeated Regulus.[1] Regulus was also a very successful stallion, becoming Champion sire eight times. Regulus also sired Careless and Cato.[2] Spilletta's dam was Mother Western, a daughter of Smith's son of Snake.[1]

Racing career


Spilletta only started one race, in April 1754 at Newmarket for a £50 Plate. She lost the race to Sir Charles Sedley's Royal, the Marquess of Hartington's Tantivy and Mr. Curzon's Jason.[3]

Stud career


Spilletta was a broodmare at the Duke of Cumberland stud. She produced five foals:

  • Ariaden – a bay filly foaled in 1759 and sire by Crab.[1]
  • Eclipse – a chestnut stallion foaled in 1764 and sired by Marske.[1] He was undefeated during his 18 race career and is generally considered one of the best horses ever. His wins included 11 King's Plates, the Great Subscription Purse and a match against Bucephalus.[3] He sired Planet, Pot-8-Os, King Fergus, Mercury, Young Eclipse, Saltram, Serjeant and Annette.[4] Eclipse is the sire-line ancestor of most Thoroughbreds alive today.
  • Proserpine – a bay mare foaled in 1766 and sired by Marske.[1] She never raced, but was the dam of Humbug and six others.[5]
  • Garrick – first called Hyperion, a chestnut stallion foaled in 1772 and sired by Marske.[1] He won a 140 guineas race at Newmarket in 1777. As a stallion he stood at Newmarket and near Malton in Yorkshire.[3]
  • Briseis – a chestnut filly foaled in 1774 and sired by Chrysolite.[1]

Spilletta died in 1776.[1]
