The early sporting artist James Seymour was born in London, the son of James Seymour Sr, a wealthy banker, goldsmith, diamond merchant and amateur artist who supplied the plate for racing trophies. The elder Seymour traded at the sign of the Flower-de-Luce in Mitre Court, Fleet Street, and was a member, with John Wootton, of the Virtuosi Club of St Luke, a gentlemen's club for artists and art lovers. Through his father, the young Seymour was introduced to the leading artists of the day. Although he had no formal art training, he learnt to draw by studying pictures and prints in his father's collection. His drawings of horses heads after Tempesta and Van Dyck are in British Museum. The contemporary diarist of the art world George Vertue set out Seymour's career as follows:
Jimmy Seymor ... from his infancy had a genius to drawing of Horses ( this he pursued with great Spirit. set out with all sorts ... The darling of his Father run thro some thousands - livd gay high and loosely - horse raceing gameing women &c. country houses. never studied enough to colour or paint well. but his necessityes - obliged him. to work or starve. thus his time passd. the latter part of his life in baseness and want of all necessaries. and dyed in Town. in the lowest circumstances & in debt - Southwark June - 1752. aged about or under 50.Seymour seems also to have bankrupted his father. Passionate about racing, he is believed to have owned racehorses himself. His earliest signed and dated racehorse painting is from 1721, from which time his output was prolific, indicating that he must have established a reputation professionally. Some of his racing and hunting scenes were engraved in the 1740s and 1750s. He counted among his patrons Sir William Jolliffe, MP, and the 6th Duke of Somerset, who commissioned him to decorate a room at Petworth with portraits of racehorses. The room decoration was never completed due to a quarrel between the artist and his patron. One of the first true sporting artists in Britain, he had no other subject matter, unlike John Wootton and George Stubbs. Seymour's obituary referred to him as 'particularly eminent in horse-painting' (Gentleman's Magazine, vol.22, London 1752, p.336).
