Paradossi per pratticare la prospettiua senza saperla, fiori, per facilitare l'intelligenza, frutti, per non operare alla cieca : cognitioni necessarie à pittori, scultori, architetti, ed à qualunque si diletta di disegno
A practical perspective manual by the Bolognese painter Giulio Troili, printed by Gioseffo Longhi in 1683 for painters, sculptors, architects and anyone drawing. Woodcut plates pair geometric construction diagrams — dotted sight lines, vanishing points, lettered triangles, receding coffered rooms and arched doorways — with foliate and fruit-laden ornamental borders, giving designers both technical line figures and repeatable frame and headpiece patterns.
