The Sexual Angle

Etymology

Lewis' surname may be connected to basalt, whose origin is the Latin basaltes, a variant of the Greek basanites, from the Greek basanos, 'touchstone' (indicating Basnight may be a metaphoric schist, a bellwether, or a barometer).

Basalt is a dark, fine-grained volcanic rock that sometimes displays a columnar structure. It is typically composed largely of plagioclase, a feldspar, with pyroxene, a prismatic crystal (Pyro- + the Greek xenos, 'stranger') and olivine.
