Prix d'Ispahan
Silvio began his stud career in England and had little impact. He was sold for £7,000 to the Duc de Castries and exported to France after two seasons and was more successful becoming leading French sire in 1886. His winners in France included May Pole (Poule d'Essai des Pouliches), Jupin (Prix Lupin) and Viennois (Prix d'Ispahan) In April 1890 he sustained a fetlock injury which became infected, and, despite veterinary treatment, Silvio had to be euthanized soon afterwards.
