held in place by visible iron hooks. Below the roof, the cornice spans around the still-visible bases of the former corner towerlets. The two-story attic is covered by the sweeping, red-tiled, late Gothic spire, in which two spire lights are set to the West and East. They are crowned by ornamental urns with pinecone knobs reconstructed in 1983 from 18th-century drawings. From atop the spire, the wooden pinnacle, copper-sheathed since 1930, rises an additional into the skies, crowned with a gilded knob and a weather vane displaying a cut-out coat of arms of Bern. Bells and bell-striker The tower's two namesake bronze bells hang in the cupola at its very top. The great hour bell, cast by Johann Reber, has remained unchanged since the tower's reconstruction in 1405. It has a diameter of , a weight of and rings with a nominal tone of e'''. The inscription on the bell reads, in Latin: "In the October month of the year 1405 I was cast by Master John called Reber of Aarau. I am vessel and wax, and to all I tell the hours of the day." When the great bell rings out every full hour, struck by a large clockwork-operated hammer, passers-by see a gilded figure in full harness moving its arm to strike it. The larger-than-life figure of bearded Chronos, the Greek personification of time, is traditionally nicknamed Hans von Thann by the Bernese. The wooden bell-striker, which has been replaced several times, has been a fixture of the Zytglogge since the renewal of the astronomical clock in 1530, whose clockwork also controls the figure's motions. The original wooden Chronos might have been created by master craftsman Albrecht von Nürnberg, while the current and most recent Hans is a 1930 reconstruction of a Baroque original. The bell-striker has been gilded, just like the bells, since 1770. Below the hour bell hangs the smaller quarter-hour bell, also rung by a clockwork hammer. It was cast in 1887 to replace the cracked 1486 original. Clock faces and façade decorations Both principal façades, East and West, are dominated by large clockfaces. The Zytglogge's first clockface was likely located on the plinth, but was moved up to the center of the shaft during the tower's 15th-century reconfiguration. The eastern clock face features an outer ring of large golden Roman numerals, on which the larger hand indicates the hour, and an inner ring on
