Lohengrin in medieval French and German romances, the son of Perceval (Parsifal). He was summoned from the temple of the Holy Grail and taken in a boat drawn by swans to Antwerp, where he rescued Elsa of Brabant from a forced marriage; he was ready to marry her himself, providing that she did not ask who he was. Elsa broke this condition and he was carried away in the swan-boat back to the Grail castle.
