Etymology: "Skiascope" is the plural of "skiascope," and the plural is a useful entry point, since each instrument is named for a shadow. The Greek "skiá" meant "shadow," and it joined with "-scope," from Greek "skopein," "to look at" or "to examine," to yield a name for an instrument that examines shadows. The word's own history is therefore compact: a Greek noun for shadow fused with a Greek suffix for seeing. Its meaning stays close to the literal, since these are instruments built around the observation of shadows rather than abstractions drawn from them.

Synonyms: shadow scopes, shadow measurers, occluders, darkness meters
