"A Recumbent, Recumbent"
Amazing object, with good light, we can clearly see the facial features, the position of the hands and legs helping, it can only be a recumbent figure. Representation of the remains of Christ, once placed in the tomb? Maybe: it is suggested to me that the angular position of the head would be due to the rigor mortis and due to the torture… and that if we position the lead recumbent figure vertically, and at a height, it always keeps watch… I will let you be the judge. Ancient object without age because I cannot find a stylistic reference.
