346th collyrium tablet (the)

Muriel Labonnelie, a researcher in Greco-Roman medical history at the laboratory of molecular and structural archaeology gives an insight into her research on collyrium tablets (also often called “collyrium stamps”).
After the discovery of the 346th specimen found during survey excavations in a dump used during the fourth century in Lyon, she traces the artefact's history and explains its role and characteristics in Greco-Roman Antiquity. Collyria were in the form of “small loaves” a small fraction of which was dissolved before administering. Collyrium tablets have inscriptions embossed in inverted order on their smaller side because they were used to mark remedies.
