And again, happy Eponalia! Seems like this is a theme amongst the posts here. :)

Happy Eponalia! 

Have you all seen the new article on Epona in Ancient Warfare (Issue IV.5)? The title of the article is 'Epona in Roman service - Military worship of a horse goddess', by Chris Lilley, principal author of epona.net.

I found a copy of the magazine in Barnes and Noble on Eponalia. Seemed very fitting.

From the Inscriptions page at Epona.net:

A rustic calendar inscribed on stone at Guidizzolo (Mantova, Lombardia, Italy) mentions the feast of Epona. [Boucher 1999, ILS 4917, RA 1892] It is now in the church of St. Martini. Guidizzolo is south-west of Verona and north-west of Mantua, and thus falls in the area of northern Italy which was formerly the province of Gallia Cisalpina.

'XV Kalendas Ianuarius Eponae'

The fifteenth day before the kalend (first) of January is 18 December.

How do you plan to celebrate Eponalia?

An interesting post Women and Horses in Mythology: Epona. Neither CR nor claiming to be (and with some factual inaccuracies, mainly deriving from the deeply flawed Wilsons Almanac entry), its mainly interesting from the personal experience point of view - Epona as protector. The poster seems to believe that Epona became a 'goddess of war' (which is not in fact the case) but then UPGs the idea that Epona is better as a protector than destroyer (which is, indeed, exactly what the epigraphic evidence tells us).

Looking over what evidence we do have to build on, the first obvious thing that strikes me is the feast day, Eponalia, 18 December (XV Kal. Ianuar). Its attested once, by a rustic calendar from Guidizzolo (Mantova, Lombardia, Italy) - which was formerly Gallia Cisalpina. The age of the inscription is not clear, first to third centuries CE.
