Happy Life
Auto-translated
Off the top of my head:
1) A verse from Manowar in Ney's signature, which, being true kings of long hair, emphasizes Scandinavian mythology in their lyrics. And Vegtamchik's signature uses Latin, if I'm not mistaken.
2) One of Odysseus's daring feats, the hero of Homer's Iliad, who appears in Pandora's signature, was that he and his surviving companions managed to escape from the cave of the ravenous shepherd-cyclops by tying themselves to the sheep and camouflaging themselves in their wool.
