How is the 11th-century poem about King Judikael connected to Old Welsh epic poetry?

The 11th-century poem written in honor of the Breton king Judikael is connected to Old Welsh epic poetry through its strong stylistic and thematic similarities. Although no literary texts in Old Breton have survived, this specific poem—attributed to a monk named Ingomar and translated from Breton into Latin—demonstrates a clear affinity with the heroic traditions found in early Welsh literature.1
