Gradlon

King Gradlon (Gralon in Breton) ruled in Ys, a city built on land reclaimed from the sea,[2] sometimes described as rich in commerce and the arts.

This character's first known appearance was in 1892 in the writings of Édouard Schuré, where she dies suddenly after Gradlon becomes king of Cornouaille, leaving him to raise their daughter Dahut.

In Guyot's version, Gradlon invades Norway and there meets Queen Malgven, who helps him enter the city and kill her decrepit, avaricious husband.

[7]Some scholars have connected Gradlon to the Breton lai of Graelent, as far back as Kerdanet's edition of Albert Le Grand's Vies des Saints.

[8] The knight Graelent, reduced to poverty after angering the queen, meets a beautiful woman at a fountain and takes her as his mistress.

Elsewhere, a cartulary of Landévennec describes Charlemagne sending ambassadors to appeal for Gradlon Mur's help.

[11] According to Amy Varin, the Landevennec Cartulary credits Gradlon with one son named Riwallon who died young.
