Main (Thompson) Library location: North wing -- Third window. The earliest records concerning the career of John Skot (alternatively spelled Scott; c. 15-- – 1537) place him in the Parish of St. Sepulchre in 1521. In this same year, the first dated books attributed to him were published: The Body of Polycye and The Justices of Peace. In 1522, Skot printed an edition of The Myrrour of Golde for the Synfull Soule translated by Margaret, Countess of Richmond, mother of Henry VII, for Wynkyn de Worde. Until the conclusion of his career in 1537, Skot worked from several presses, where he published titles including Commendations of Matrimonie, Nicodemus Gospel, The Nut Browne Maid, and Rosary. Skot's most frequently used device had two variations. The simple mark displayed in the Vassar Library is comprised of his initials I.S., in the orb of an orb-and-cross design. Just below the horizontal bar of the four-mark is a small letter S. Typically, the entire woodcut depicted his mark in the center of a shield beneath a helmet, presented by two griffin-like creatures. In 1530, Skot replaced this mark with a more elaborate monogram in the center of the shield.
