Pedigree
Sir Hercules was by the great sire Whalebone, winner of The Derby, out of Peri (1822) by Wanderer. Peri was bred to Whalebone at the age of three and Sir Hercules, her first foal, was born in 1826 at Petworth Stud. Sir Hercules was a half brother to Langford (by Starch) who was exported as a stallion to America.
Black with white ticking, Sir Hercules was 15 hands 2 inches high, and had a compact build, with identical length "...From the centre of the breast to the hind part of the shoulder, from hind part of shoulder to the hip, and from hip to whirl-bone," with "no more than room for a saddle on his back."
