sentences:  Aside from his lasting friendship with Poussin, who shared his antiquarian interests and from whom Cassiano commissioned the series of seven "Sacraments" and the illustrated manuscript of Leonardo's "Le Regole e Precetti della Pittura", Cassiano's patronage extended to the French painter in Rome Simon Vouet and the classicizing sculptor Alessandro Algardi, to Artemisia Gentileschi, Gian Lorenzo Bernini (from whom he commissioned a bust of his uncle, Carlo Antonio), Pietro da Cortona, Caravaggio as well as lesser-known contemporary artists whom he kept busy with lesser commissions for his "Museo Cartaceo".His close connections with leading European scientists such as Galileo, with scholars and philosophers, kept him fully informed of the latest archaeological and scientific discoveries, for all of which he attempted to provide a visual record in his "Museo".Cassiano also appears to have patronized the publication of manuscripts on painting by Matteo Zaccolini.
