Late Medieval Pewter Badge

Interesting piece whatever it is.

Two things struck me for what it may be worth. How about William and Mary as a monogram? And are the ends depicting Lion's feet perhaps? A sign of strength and stability. Probably way off, but an interesting object, possibly contact the Royal Museum and inquire?

Thanks for all your replies! It's possible it could be William and Mary. I've read, though, that this type of badge died off after the mid Tudor period.
I know it's usually bad form to post links, but this is an excellent example of the Marian Monogram (crowned M) that the badge reminds me of. What do you all think?

Keep in mind that it may not be symbolic at all, and is just an artistic jewelry design chosen for a brooch or badge -- sometimes we look for symbolism that isn't there.

That being said --

It reminds me of what are known as pilgrims' badges. The time frame is certainly correct; the English origin, plausible.

The Canterbury Tales is a good example: a group of pilgrims all meet in an inn on their pilgrimage to the holy shrine of St. Thomas a Becket (martyred Archbishop of Canterbury), a pilgrimage undertaken by each traveller for his or her own reasons, but often especially by those who recovered from illness after praying to the Saint.

"Thanne longen folk to goon on pilgrimages" -- "then" being April or early May -- pilgrims would go to venerate various saints at the cathedrals and churches which the saint was associated with and which usually preserved a holy relic, such as a shroud, a bone, a trinket, or some other connection between the physical and spiritual. In England, Canterbury was a pretty popular pilgrimage; Spain had the Camino de Santiago, i.e. Santiago de Compostela. Not all pilgrimages were voluntary; many were undertaken in penance or repentance. A town's cathedral being chosen as a home for holy relics was not only a major boon to tourism, it was a source of steady income from pilgrims.

Once the weary pilgrim (no horses, that's cheating!) got to Canterbury or wherever, they would find an abundance of cheap trinkets, souvenirs and such being sold, including pilgrims' badges. These badges not only served as a memento of your pilgrimage, they also served as proof that you had completed the journey, and furthermore, could be collected as a show of piety (sort of like Boy Scout merit badges, but for religious devotion.)

Not sure what exactly this one is supposed to represent, or if it's even that sort of badge, but I like the theory of the crowned M or double M (e.g. Maria Mater). A large time investment on Google Images might pay off if you can find something that is close to this one.
