Plague (and resulting famine) was very bad in the 14th century. Very bad.
I can see why talismanic symbology, especially talismans that protected you if they were carried (even if you couldn't read them), and which "blessed" you (in the sense of last rites) so you could go to heaven without intervention by a priest, would be REALLY popular.
Birthing talismans were probably always popular, not just in plague times. Giving birth was hazardous any time.
The Arma Christi was both.
