Tome premier.
This Tome premier is a French architectural treatise of plans and elevations, held by the Stiftung Bibliothek Werner Oechslin in Einsiedeln, with its record giving no author, date or intended readers. The four plates show labelled ground plans of rectilinear halls and rooms, with letter keys, thick black walls, colonnaded entrances and sparse hatching. A designer could take from them a clear diagrammatic vocabulary for floor plans, with thick wall masses, lettered keys and simple column rows.
