Small limestone bas-relief of petrifying fountains, antique scene, vintage

Very pretty small square bas-relief, rare scene, in limestone from the petrifying fountains of St Nectaire, dating from the 50s-60s. Square plaque, relief in the center representing an antique scene: a woman, priestess or goddess, appearing to place offerings in a cauldron, probably for divination or prayer. Beige color. Dimensions: 14x14 cm, approximately 1 cm thick. Very detailed and fine decoration. This type of format requires between 7 and 10 months of deposit in a petrifying fountain. Very good general condition, some small chips on the edges, especially at the top, and a discreet chip at the bottom. Attachment on the back for wall hanging, can also be framed. Weight approximately 500g.
