“This book makes a very valuable contribution to the knowledge and positioning of Della Porta in the history of optics. … The Optics of Giambattista Della Porta is a must for anyone interested in the problems of optical practitioners of around 1600.” (Huib J. Zuidervaart, Journal for the History of Astronomy, Vol. 50 (2), 2019)“The Optics of Giambattista Della Porta (ca. 1535–1615) is relevant to scholars interested in perennial issues arising out of classic Scientific Revolution scholarship (the mathematization of nature, the development of scientific laws, experiment versus experience, and so forth), natural magic, early modern optical technology, early modern diagrams, and epistemic images generally.” (Tawrin Baker, Isis, Vol. 110 (2), June, 2019)
