Lancet-window
Lancet-Window
is an architectural term for a narrow window with acutely-pointed arch head. This form was much used in England and Scotland during the early pointed period of Gothic architecture. Several lancet-windows are frequently grouped together, so as to produce a pleasing effect. In Scotland. the lancet-window was, like many other features of Scotch Gothic, retained to a much later period than in England. — Chambers, Cyclopaedia, s.v.
