FORTUNA is the Roman Goddess of Luck, Fate, and Fortune, as Her name implies. She was a very popular Goddess, and was worshipped under many epithets depending on the type of luck one wished to invoke or the circumstances in play. She had many temples in Rome itself, as well as having important cult-centers in Antium (the modern Anzio), a city on the west coast of Italy about 30 miles south of Rome, and Praeneste (modern Palestrina), about 20 miles south-east of Rome, both of which were cities of Latium, the land of the Latini tribes. Her many temples in Rome, and the various aspects of Her worship are a reflection of the manners in which She was honored: from personal Goddess, overseeing the fate of the individual mother, young man, or soldier, to a Goddess of the State, ensuring the fortune of the populace, the luck of the Emperor, or the glorious fate of the entire Roman Empire.
The name Fortuna finds its root in the Latin fero, meaning "to bring, win, receive, or get". She may have originally been a Goddess of Fertility, Who brought prosperity and success in the form of abundant harvests and offspring. Her worship in Rome traditionally goes back to the time of Ancus Martius, the 4th King of Rome, who is said to have reigned from 640-616 BCE. According to the propaganda of the time (and the Romans invented an awful lot of it to make it seem that their city had always been destined for greatness, and wasn't just some upstart town founded by a bunch of sheep herders on some hills surrounded by malaria-infested swampland, which it was), when Fortuna first came to Rome, She immediately threw off Her shoes and discarded Her wings, announcing that She'd found Her true home and intended to never leave it.
The Emperor Trajan (97-117 CE) dedicated a temple to Fortuna, at which offerings were made to the Goddess on the 1st day of January, at the start of the New Year, probably to ensure good luck and success for the coming year. This temple was dedicated to Fortuna in all of Her aspects.
