Specimens of Gothic architecture, consisting of doors, windows, buttresses, pinnacles, &c. : with the measurements, selected from ancient buildings at Oxford &c.
Frederick Mackenzie's 1825 London architectural study, published by J. Taylor, records Gothic doors, windows, buttresses and pinnacles measured from Oxford buildings, meant for architects and draughtsmen. The plates are precise line engravings: a tracery-railed chapel arch, a rotated panel of lancet window tracery, a classical colonnade of clustered columns, and a tall spired tower, offering a designer clear models of pointed arches and openwork stonework.
