Above is a detail of a stipple engraving of the great mathematician and astrologer, John Dee. It is simply titled “Dr. John Dee” (1527-1600), and was published and printed in London by T. Cadell, 1798. This is a very fine portrait (5×4″ on a 7×5″ sheet) undertaken in an accomplished/naive style after the painting by George Perfect Harding (d. 1868) and engraved by Nicolas Schenker (1760-1848). [We offer the original (pictured below) at our blog bookstore, here.]
