John Calvin (Iohannes Calvinus.)

Circa 1690 engraving of John Calvin (Iohannes Calvinus), the French-born theologian and central figure of the Protestant Reformation, shown in a half-length portrait based on an earlier 16th-century likeness. Printed on laid paper, the work retains a period feel with a manuscript annotation in 17th-century Dutch written neatly below the image, likely devotional or biographical in nature.
