Jacobus de Voragine
The "Legenda Aurea" of Jacobus de Voragine, compiled about 1260 and one of the most-read books of the High Middle Ages, gives sufficient details of the saints for each day of the liturgical year to inspire a homily on each occasion. The very brief "vita" of St Valentine states that he was executed for refusing to deny Christ by the order of the "Emperor Claudius" in the year 269. Before his head was cut off, this Valentine restored sight and hearing to the daughter of his jailer. Jacobus makes a play with the etymology of "Valentine", "as containing valor".
