Taran Noah Smith, who played Jonathan Taylor Thomas's younger brother on Home Improvement, was named after Taran, the assistant pig keeper who becomes High King in Lloyd Alexander's Chronicles of Prydain. And a dozen other fantasy novels drew from Celtic myth.
But was there any gay symbolism? Any suggestions that the Celtic world might be a "good place"?
They travel together, until finally the wanderer gives his life for the bard. Then he remembers: he is Manawyddan, God of the Ocean, and the bard is his fellow god Pryderi in disguise. His quest required him to sacrifice himself for a friend (and the amnesia was necessary, lest he remember that he was immortal).
The source was The Book of the Three Dragons, by Kenneth Morris (1930), which recounts many adventures of the Manawyddan and Pryderi. Both marry women, but their love for each other is strong enough to save the world.
By the way, when the magician Gwydion and his brother Gilvaethy stole Pryderi's pigs, the High God Math turned them into various animal pairs (boars, deer, wolves). At the end of each year, they brought him an animal sacrifice, and he turned it into a beautiful boy. A same-sex couple having children!
And Cuchulain, who single-handedly defeated the army of Ulster at age 17, depicted here as a muscular Conan-style barbarian: he was so beautiful that everyone who saw him desired him. The sagas mention both male and female lovers. For instance, Ferdia:
Fast Friend, forest companions,
we made one bed and slept one sleep
In foreign lands after the fray.
Scathach's pupils, two together.
