The Mace, a symbol of authority dating back to medieval times, when it was a studded, club-like weapon that was made of iron and could break armor. It later would be used in processions of city mayors and other dignitaries, and became an emblem of order and authority during academic ceremonies. The staff of IU's Mace is 30 inches long and made of polished ebony encircled with four brass, gold-plated collars and entwined by swirled gold bands. Atop the staff is a globe of plated brass with four flat sides. The sides of the globe are embossed with IU's seal, the seal of the state of Indiana, the emblematic initials "IU," and the donor inscription. The Mace was presented to the university by Indiana Alpha of Phi Delta Theta in 1949. Mounted on the globe of the Mace are 12 large synthetic jewels of blue sapphire, ruby, garnet and topaz. Atop this rests an eagle with outstretched wings.
The Jewel and Chain of Office is worn by the university president at ceremonial occasions. The Jewel of Office is handcrafted of gold-plated sterling silver and precious jewels. Each part of the design has a symbolic meaning that reflects IU's historic origin and educational mission, noting such things as the number of states in the Union when the university was founded in 1820 (22 states), the year Indiana became a state (1816), and the years that mark IU's evolution from a seminary to a university (1820, 1828 and 1838). The jewels in the item include emeralds, sapphires, topaz, rubies and diamonds. The Jewel of Office was presented to the university in 1946 by the Pi chapter of Beta Theta Pi. The Chain of Office was donated to the university in 1958 by the Lambda chapter of Sigma Chi. The chain is handcrafted of gold-plated sterling silver and contains 44 linked panels, eight of which are engraved with the names of the presidents who have served the university since the Jewel of Office was first worn as the symbol of the presidency.
