Magnum in parvo, or, The marrow of architecture : shewing how to draw a column with its base, capital, entablature, and pedestal : and also an arch of any of the five orders ... according to the proportions laid down by ... Palladio ...
Magnum in parvo is a 1728 London architectural manual by William Halfpenny, issued by booksellers John Wilcox and Thomas Heath, that teaches draughtsmen to construct the classical orders from Palladio's proportions. The pictures are measured engraved plates of columns, bases, capitals and entablatures set beside numbered diameter scales, showing how each order is divided into parts. A designer might take from them the crisp hierarchy of classical column proportion and the precise, diagrammatic layout of an elevation with its scale of modules.
