Happy Day of Epona! 🐴 🌹 ❄️
As far as I can tell, the 1st publication to use "Eponalia" is "The Wicca Book of Days" (Dunwich, 1995). While it is a sensible analogy to Saturnalia and Opalia (the days before and after), the Guidizzolo fragment writes out "Saturnalia," but leaves the next day as just "Epone".
