the.com/speculum
A duck-billed metal stranger that's been making patients flinch for two thousand years.
means A medical instrument inserted into a body cavity and opened to hold it apart so a doctor can see and examine inside.
from Straight from Latin speculum, "mirror" — itself from specere, "to look at" (the same root that gives us spectacle, inspect, and spectator). The word's earliest sense was literally a polished surface for seeing, and the medical tool borrowed the name because it, too, was about looking — opening a passage to let the eye in. Archaeologists have found bivalve and screw-driven speculums in the ruins of Pompeii, which is why the two-thousand-year claim holds up.
