Violoncello was a notable Australian Thoroughbred race horse.
Bred in England where he had raced six times for three wins, he was purchased as a seven-year-old for 4,000 guineas by Sir Samuel Hordern and sent to Australia.
Grandsire Laveno (GB) won the 1895 Great Britain Champion Stakes and Jockey Club Stakes.
His half-brother, Quinologist had won the 1916 AJC Metropolitan Handicap which influenced Hordern to purchase him.
Violoncello won the 1921 Caulfield Cup and the inaugural running of the Cox Plate in 1922.
