La perspective speculative, et pratique : ou sont demonstrez les fondemens de cet art, & de tout ce qui en a esté enseigné jusqu'à present : ensemble la maniere vniverselle de la pratiquer, non seulement sans plan geometral, & sans tiers poinct, dedans ni dehors le champ du tableau : mais encores par le moyen de la ligne, communément appellée horisontale
A French treatise on the theory and practice of perspective begun by Jacques Aleaume and completed by Estienne Migon, printed in Paris in 1643 by Tavernier and Langlois for painters, architects and surveyors. Alongside ruled perspective diagrams, the pages carry woodcut initials filled with acanthus scrolls, roses and field flowers, and friezes with grotesque masks, usable as ornamental letters, rules and band borders.
