The New Student's Reference Work/Amadeus

Amadeus, a name very common in the ruling family of Savoy. Those of the name most famous were: Amadeus V, Count of Savoy (born 1249, died 1323), called the Great. His most celebrated exploit was his repulse of the Turks from the Island of Rhodes, then held by the Knights of St. John. In memory of this victory, a Maltese cross, with the letters F. E.  R.  T. (Fortitudoe ejus Rhodum tenuit—"His bravery saved Rhodes,"), was made the coat of arms of the family. Amadeus VIII, count and first duke of Savoy, was born 1383, and died 1451. After a few years of rule, he retired to a monastery, Ripaille, where he lived a life of luxury. In 1439, he was elected to succeed Pope Eugenius IV, who had been deposed, but after a few years he resigned in favor of Nicholas V. As pope, he was called Felix V.
