Strenua

In ancient Roman religion, Strenua or Strenia was a goddess of the new year, purification, and wellbeing. She had a shrine (sacellum) and grove (lucus) at the top of the Via Sacra. Varro said she was a Sabine goddess. W.H. Roscher includes her among the indigitamenta, the lists of Roman deities maintained by priests to assure that the correct divinity was invoked in public rituals. The procession of the Argei began at her shrine.

On January 1, twigs from Strenua's grove were carried in a procession to the citadel (arx). The rite is first noted as occurring on New Year's Day in 153 BC, the year when consuls first began assuming their office at the beginning of the year. It is unclear whether it had always been held on that date or had been transferred that year from another place on the calendar, perhaps the original New Year's Day on March 1.

The name Strenia was said to be the origin of the word strenae (preserved in French and Italian strenne), the new-year gifts Romans exchanged as good omens in an extension of the public rite:

From almost the beginning of Mars' city the custom of New Year's gifts (strenae) prevailed on account of the precedent of king Tatius who was the first to reckon the holy branches (verbenae) of a fertile tree (arbor felix) in Strenia's grove as the auspicious signs of the new year."

During the Principate, these strenae often took the form of money.
