The one who was not burnedpan-Hindu
Prahlada's aunt Holika was said to be proof against fire and carried him into it to kill him. She burned and he did not. The bonfire lit on this night is that fire, and what it commemorates is the reversal rather than the flames — the protection that was supposed to be hers turned out to be his. Effigies of Holika are commonly placed on the pyre and burned with it.
