Casseri was one of the principal representatives of the golden age of anatomy at Padua. He was pupil, assistant, and eventually deputy to Fabricius, and would have succeeded him as chair of anatomy had he not predeceased his master. De vocis auditusque is a comparative anatomy of the vocal and auditory organs in humans and a variety of animals. The thirty-four large plates, engraved by Joseph Maurer, under the direction of Casseri, are based on extensive dissections. The work includes a detailed account of the larynx, and the first accurate description of the laryngeal muscles and nerves. The extravagent baroque title page, engraved by Jacopi Ligozzi, includes the skeletons of two cherubs.
