Edwards' tombstones, hand carved by The John Stevens Shop, were installed in the college's basement. Sculpture Sculptures have adorned the courtyard since its opening. In the 1930s, the courtyard featured an early eighteenth-century bronze statue of a young slave holding a sundial, purported to have belonged to Elihu Yale. It has since been transferred to the Yale University Art Gallery. In 2012, a bronze sundial honoring Master Gary Haller was installed near the site of the original sundial, bearing the crest and badge of the college. Since 1998, the Yale University Art Gallery has loaned a twelve-foot bronze sculpture by Dimitri Hadzi, entitled "Floating Helmets", to the Head's Courtyard. The JE Press JE is one of two residential colleges which maintains active use of its print shop, the JE Press. JE owns three manual press, one of which belonged to Frederic Goudy, and an automated Vandercook press. The JE Press is overseen by printer Richard Rose, who teaches classes each year in the printing arts. Exhibitions The work of artists affiliated with the college are on rotating display their art in the college's basement art gallery. A permanent installation of prints by Walker Evans can also be found in the basement, as well as historical memorabilia and ephemera printed by the JE Press. Insignia The official insignia of JE is its shield, described in heraldic terms as ermine, a lion rampant vert. Designed by Fritz Kredel, it is a simplified version of the coat of arms believed to have been used by the Edwards family. A green, rearing heraldic lion symbolizes courage and purity of heart. Its crimson tongue and nails exhibit willingness to pursue its goals with passion both of speech and strength. The veil of white that surrounds the lion symbolizes the grace of God. This shield is used on formal decorations and college letterhead. Other insignia have been informally adopted for the college. A red apple surrounded by a green serpent, a reference to the Book of Genesis, is used on blazers and other college apparel. It recalls the Reverend Jonathan Edwards' preoccupation with the doctrine of original sin. It was devised by the first Master and Fellows, and designed by H. Dillington Palmer. It forms the silver head of the ebony mace of the College. The college's mascot is the Spider, derived from a line in Jonathan Edwards' early descriptive writings on the creatures as well
