This stone block belonged to Gaius Silvius Tetricus. He was an eye doctor - oculist who probably came from France. His name and four different medical preparations for the relief of eye troubles are recorded around the four sides. The lettering is written in reverse, as the stone was probably used to stamp sticks of ointment. Each narrow side of the block is carved with a different prescription. 'Gaius Silvius Tetricus's remedy for eye disease and corneal scars'; 'Gaius Silvius Tetricus's application for eye inflammation'; 'Gaius Silvius Tetricus's fragrant lotion for soothing sore eye lids'; 'Gaius Silvius Tetricus's ointment for attacks of conjunctivitis'.
