Februus

Februus is the Roman god from whose purification rites the month of February takes its name...

Hence the month of February was also sacred to Juno, the goddess of marriage, and she was therefore surnamed Februata, or Februtis. (Fest. s. v. Februarius; Arnob. iii. 30.)...

For the Etruscans, Februus was also the god of riches (money/gold) and death, both connected to the underworld in the same natural manner as with the better-known Roman god Pluto...

The name Februus is connected with februare (to purify), and februae (purifications). 

Another feature in the character of this god, which is however intimately connected with the idea of purification, is, that he was also regarded as a god of the lower world, for the festival of the dead (Feralia) was likewise celebrated in February...
