Grosvenor's Arabian [probably Eaton Barb] ch c 1760c. Sire Line Grosvenor's Arabian.

Richard, 1st Earl of Grosvenor (1731-1802), owner of the famous and extensive Eaton stud in Cheshire, was said to have made nearly £200,000 on the racecourse although he is also reputed to have spent £250,000 in the endeavour. He was among the first patrons of George Stubbs, "the horse painter". Three Derby winners (Rhadamanthus, John Bull and Daedalus) and five Oaks winners (Faith, Ceres, Maid of the Oaks, Nike and Bellina) ran in his orange-jacket, black-cap colours.

Lord Grosvenor also owned such notable turf performers as Gimcrack (gr c 1760 Cripple), Mambrino (gr c 1768 Engineer), Pot8os (ch c 1773 Eclipse), Protector (br c 1770 Matchem) and Sweetwilliam (ch c 1768 Syphon), and was the breeder of Sweetbriar (ch c 1769 Syphon). His eminent stallions included John Bull (ch c 1789 Fortitude), Alexander (ch c 1782 Eclipse) and Meteor (ch c 1783 Eclipse).

In his portrait the Grosvenor Arabian is shown as a chestnut with high stockings and a blaze extending down over his lips and he may well be an early example of sabino colouring. He sired a number of offspring, most of them for Lord Grosvenor, and most of them dating from the late 1760s to the early 1770s. Although he had no lasting influence on bloodstock breeding, his son Euryalus (ch c 1767) won four Royal Plates and defeated such horses as Conductor (ch c 1767 Matchem) and Trentham (br c 1766 Gower's Sweepstakes). Under the name of the Eaton Barb he sired one unnamed filly. None of his offspring have descendants recorded in the General Stud Book.
