She was said to have been born in Carthage or Teniza (presently Ras Djebel, Tunisia) and martyred under Roman Emperor Diocletian.

[3] A later medieval legend, recounted by Pietro Suddiacono in the 10th century[4] and similar to legends associated with Devota, Reparata, and Torpes of Pisa, states that after being horribly tortured, Restituta was placed in a blazing boat loaded with oakum and resin.

The legend further states that a local Christian woman named Lucina had dreamt of the angel and the boat.

When she walked to the beach, she found the resplendent and incorrupt body of Restituta, who was now dead.

[3] Lamartine, inspired by the legend of the saint, composed in 1842 “Le lis du golfe de Santa Restituta dans l’ìle d’Ischia.”[3] The largest city square in the Italian town of Sora, the Piazza di San Restituta, is named after the saint.
