Lippant
In Wolfram’s Parzival, the duke of Bearosche and vassal of King Meliant of Lis, whom he raised. His daughters were Obie and Obilot, his brother was Duke Marangliez of Brevigariez.
King Meliant fell in love with Lyppaut’s daughter Obie. When Obie rejected him, Meliant declared war on Lyppaut. Gawain happened upon Bearosche and agreed to give Lyppaut his aid. In battle, Gawain captured Meliant and delivered him to the girl Obilot. Obilot transferred him to her sister, the two reconciled, and the war ended.
Lyppaut’s counterparts are Tiebaut in Chrétien’s Perceval and Leigamar in Heinrich von dem Türlin’s Diu Crône.
