“Feronia’s themes are fertility, abundance, earth, freedom, sports and recreation. Her symbols are fire and coals. This Roman fire Goddess provides fertility and abundance during even the harshest of times. When boredom sets in, she arrives with arms bearing festive energies and earth’s riches as a ‘pick-me-up’. According to Roman tradition, She is also the patroness and liberator of slaves, or of anything that allegorically enslaves us.
Every November 13, the Plebeian games opened in Rome with all manners of sport competitions. This festival also honored the Goddess Feronia and her liberating nature. Mirroring this theme, get outside and do something physical to release any anger or tension you bear. Give it into Feronia’s care so She can transform it into healthful energy.
Carry a piece of coal today to generate a little of Feronia’s abundance in all your efforts. Keeping this near your stove (or any fire source, like the heater) maintains this Goddess’s energy in your home year-round. If a day comes when you have a really pressing need, burn the coal in Feronia’s liberating flames to release the magic for fast manifestation.
If you find your inner reserves waning with the winter’s darkness, light a candle sometime today to invoke Feronia’s vitality. Better still, light it for a few minutes each day until you feel your energy returning.”
(Patricia Telesco, “365 Goddess: a daily guide to the magic and inspiration of the goddess”.)
“Feronia was a Goddess broadly associated with fertility and abundance. She was especially honored among plebeians and freedmen. Her festival, the Feroniae, was November 13, during the Ludi Plebeii (“Plebeian Games“), in conjunction with Fortuna Primigenia; both were Goddesses of Praeneste.” 
Patricia Monaghan wrote that “far from the growing cities of Italy, this solitary Goddess made Her simple home in woodlands like those at Campania or at the foot of mountains like Soracte. She may date to the era before Rome some believe She is a vestigial Etruscan Goddess, powerful enough to maintain Her own identity after Roman conquest, for Her major sanctuaries were in the central Italian areas where the Etruscans once lived. Orchards and fields, volcanoes and thermal springs were Her abode, for She was a fire Goddess ruling the heat of reproductive life as well as the fires beneath the earth’s crust. At Her festivals on the Ides of November, great fairs were held and first fruits offered; freedom was bestowed on slaves; men walked barefoot across coals to the cheering of crowds.
The energy of Feronia could not be contained within cities, and Her sanctuaries were therefore in the open country. So unsociable was She that when Her Campanian forest shrine once burned and Her worshipers planned to remove Her temple to the safety of a town, the Goddess instantly restored the charred trees to leafy greenness” (p. 124 – 125).
