Uterine gems belong to a group of amulets, usually engraved on red minerals, such as jasper and carnelian; the most used is the hematite or “blood stone”. The iconography of the uterus in these gems refers to the mobility of the uterus, an idea already present in Plato's Timaeus (Pl., Ti.  91c.), and in the Greco-Roman medical texts, the wandering uterus theory. In this work we will complete the analysis of uterine gems with the use of stones as a therapeutic in the work of Oribasio de Pérgamo.
