It was a Greek of the time of Alexander the Great, in the century following that of Pheidias, who invented the art of taking casts from the human form. This honor, according to Pliny, belongs to Lysistratus, a near relative of the famous sculptor Lysippus, who made life casts with such infinite skill as to produce strikingly accurate resemblances. The art of making life casts did not, however, come into general use until the middle of the fifteenth century, when Andrea Verocchio, the most noted pupil of Donatello, and the instructor of Perugini and of Leonardo da Vinci, followed it with such success as to lead Vasari, Bottari, and others to ascribe to him its invention. It was this art of taking casts from the human form, so successfully followed in this country, nearly four hundred years later, by John Henri Isaac Browere, that has afforded the occasion for the present work. II _The Plastic Art in America_ Before entering upon the subject of Browere and his life masks, it seems proper, if not actually necessary, to take a survey of the development of the plastic art in that part of America now embraced within the limits of the United States, prior to the time of Browere, so as to understand what influences may have been exerted upon him in the direction of his career. This becomes the more important from the fact that while there have appeared in print, from time to time, numerous references to this subject, not a single consideration of the topic, known to the writer, has presented the facts with that accuracy without which all deductions must be in vain. From the present consideration the plastic work of the aborigines is necessarily excluded, as it belongs to another and very different department of study; this having to do with a branch of the fine arts, and that with a phase of archæology. Prior to the war of the Revolution, while there were among us several painters exercising their art, both those of foreign and those of native birth, no note has come down of any modeller or sculptor in our midst, save one--a very remarkable woman named Patience Wright. It may be that we had no need for the sculptor’s art. We were mere colonies without call for statues or for monuments. It is true there was the leaden figure of King George, on the Bowling Green, in New York; but it came from the mother country, and soon furnished bullets for her rebellious sons. Likewise came from across the ocean the odd bits of decoration intended as architectural aids in the building of old Christ Church, in Philadelphia, and of a few other noted buildings. But our first practitioner of the plastic art was, as has been said, a woman.
