Octavii Ferrari de re vestiaria, libri septem : quatuor postremi nunc primum prodeunt : reliqui emendatiores & auctiores ..
This is a 1654 Latin treatise on ancient Roman clothing by Ottavio Ferrari, printed in Padua for scholars and antiquarians. The pictures are engraved plates of draped classical figures in togas and tunics, many based on statues. A designer could take from them the structure of Roman drapery, with its folds, weight and the way cloth wraps the body and falls from the shoulder.
