Лузиады
"Lusus" is usually translated as "game" or "play", while "lyssa" is a borrowing from the Greek λυσσα, "frenzy" or "rage", and sometimes Rage personified; for later poets, Lusus and Lyssa become flesh-and-blood companions (even children) of Bacchus. Luís de Camões' epic "Os Lusíadas" (1572), which portrays Lusus as the founder of Lusitania, extends these ideas, which have no connection with modern etymology.
