John “H.B.” Doyle learned to paint landscapes under Gaspare Gabrielli, and miniature portraits at the Royal Dublin Society's drawing school under John Comerfield. He won a gold medal in 1805. He was commissioned to paint equestrian portraits of the Marquess of Sligo and Lord Talbot, the Irish viceroy, and in 1822 he produced six prints entitled The Life of a Racehorse. His painting “Turning out the Stag” brought him recognition when it was exhibited at the Royal Academy in 1825.
