What is "polymelus"

Polymelus (1902–1924) was a British Thoroughbred racehorse who was the leading sire of racehorses in Great Britain and Ireland for five years (1914, 1915, 1916, 1920, 1921). Among his most famous descendants are Secretariat and Northern Dancer. However, it was through his son Phalaris that he will forever be remembered. His great grandsire was Bend Or.

The skeleton of Polymelus is now on display in the entrance lobby of the University of Cambridge Museum of Zoology, where it is an example of the specialised adaptations to high-speed running.
