This is another illustration based on Irish mytholigy, this time the story of Tir na nÓg, In short the story takes place around a young Irish warrior fella called Oisín who sets off to the land of the young and beautiful 'Tír na nÓg', I'm guessing some Nordic country! There's a love story but I'll skip that. Anyhow, he been a mighty warrior misses the craic with the lads back home. He is allowed to return to Ireland on a great white horse but is warned never to touch the ground.....(spoiler alert) He falls, ages 300 years and dies.... as that is the length he has been gone. 

Oisín when he ages 300 yeaars.
