The hagioscope provided a view of the altar for those seated in the transept.
Hagioscope → It is formed from "hagios" (from Greek ἅγιος, meaning holy or sacred) and "scope" (from Greek σκοπός, meaning to look or to view). The word refers to a viewing place for observing the holy or sacred, particularly in a church context.
Think of 'holy' ('hagios') and 'to look' ('scope') — a hagioscope is a place to look at something sacred.
