Two entries with the name Antonio.
Antonio’s son later encountered Tristan in Cornwall, and tried to slay him with a poisoned arrow. He succeeded only in wounding Tristan, who slew him for the deed.
The knight is named only in the Italian La Tavola Ritonda, though this episode appears in the Prose Tristan and in Malory’s version.
