nursemyra is always on the lookout for
instruments of torture medical instruments. whilst grateful to be living in an era of advanced technology, I have a deep appreciation for the fine craftsmanship of earlier tools such as those featured here
however this speculum does bear more than a passing resemblance to a corkscrew opener.
One of the most spectacular, if fearsome looking, Roman medical instruments is the vaginal dilator or speculum (dioptra). It comprises a priapiscus with 2 (or sometimes 3 or 4) dovetailing valves which are opened and closed by a handle with a screw mechanism. Soranus is the first author who makes mention of the speculum specially made for the vagina.
I’m tempted to speculate that the followers of Soranus may have mistakenly used it to dilate another orifice.
