SINOPIE
Sinopia, a dark reddish-brown pigment, was widely used in Classical Antiquity and the Middle Ages for painting and for drawing on walls when producing frescoes. The term is used both for the pigment and for the preparatory drawings themselves, sinopie, which we sometimes see when frescoes are stripped from walls for transfer onto canvas. See Learn More for Cennino Cennini’s description of the technique.
ARCHITECTURAL DRAWINGS
Few architectural drawings survive and differences between them and the finished buildings they portray make them difficult to interpret. As one scholar has commented, it is as architects were determined to preserve the secrets of their workshops. Perhaps the most extraordinary architectural drawing we know today is the design for a façade for Barcelona Cathedral, produced in 1408 but not executed until the late 19th century when a new campaign of building was undertaken in the city’s Gothic Quarter.
MODEL BOOKS
The most famous album of model drawings from the period is that of the architect and stonemason Villard de Honnecourt (ca. 1225-ca. 1250). The purpose of the album is the subject of controversy. Originally it was thought to have served as a training manual for architects, but scholars now think the models were mnemonic devices for architects to remember things they had learnt orally. Another type of model was portrait-like facial types, like the Bearded Prophet below, that could be incorporated within a variety of compositions.
