One of the votive inscriptions to these goddesses reads: Mars Thincsus is correlated with the Germanic war-god Týr. The latter was associated with oath-taking and the Thing, a local assembly of free men. Political issues were discussed, judicial decisions were made, and religious rites were held there. Scherer suggests that they came from the district of Twenthe in the province of Overijssel, Netherlands.
Second inscription
The second inscription reads:
Syncretism
The goddesses called the Alaisiagae are named on altar-stones from the same fort on Hadrian's Wall as being parallel with two Germanic goddesses: Celtic Boudihillia is equated with Germanic Fimmilena and Celtic Beda is equated with Germanic Friagabis. These parallel goddesses are taken to be Germanic not only because of clues in the inscriptions and the Germanic mercenaries at the wall at the time, but also because they both have an initial ‘f-,’ a sound not known to have developed in Celtic at this time. Equally, the two goddesses are not known to be Roman. Beda may have been an abbreviation for Ricagambeda since the two names share similar semantics. Boudihillia and Beda are more likely Celtic names however.
Archeological setting
The altar stones of the Alaisiagae were recovered in the Temple of Mars at Vercovicium. This roughly circular temple was found on top of Chapel Hill a little to the south of the fort, its walls of undressed stone facing with an earth and rubble infill enclosed an area measuring about 17¼ ft. across. The insubstantial foundations indicate that the superstructure was at least half-timbered. The temple was built in the early-3rd century upon the ruins of a rectangular workshop in the vicus which had been destroyed during the barbarian incursions of AD196. It contained altars dedicated by the commanders and men of all three units known to be stationed at Vercovicium to the god Mars Thincsus, the Romanized aspect of a Teutonicgod, a common occurrence among the Roman auxiliary units. Various altars have been found at this site dedicated to Mars and/or to the Celto-Germanic goddesses Alaisiagae; named on one altar as Beda and Fimmilena, on another as Boudihillia and Friagabis.
Etymology
Boudihillia can be derived from the Proto-Celtic*Bōud-ī-hīlījā meaning 'victory's fullness.' Beda is derived from the Proto-Celtic *Bed-ā meaning 'burial.' Alaisiagae is derived from the Proto-Celtic *Ad-lājsījā-agai meaning 'sending fears,' plausibly a byword for a notion of “dispatching terrors”.
