Acoustics

A faint, oval-framed copperplate engraving shows a man, likely a scholar or legal professional. He has a mustache and a small goatee. He wears a dark cap, perhaps an academic bonnet, and a dark gown with a broad, flat white collar typical of the mid-17th century. A blue ink library stamp is positioned over the center of the portrait.

The prominent mirrored text across the page is show-through from the text printed on the reverse side. This reverse text identifies a "Legal Dissertation" original: "DISPUTATIO JURIDICA" presided over by Ernst Friedrich Schröter (1621 to 1676) and printed in Leipzig original: "LIPSIAE" around 1661.
