Bispira volutacornis, sometimes known as the twin fan worm or spiral fan worm, is a type of tube worm found in the shallow sublittoral zone of the eastern Atlantic Ocean. It grows in crevices and in stony areas and prefers areas rich in sediment but with low levels of illumination. It has a parchment-like tube with a mucoid outer layer that is often coated with mud or silt. The tube is usually concealed in a crevice and the worm can retract into the tube when disturbed. It feeds on plankton which it captures with its plumes. It also uses the plumes to gather sediment with which to expand the tube. This B. volutavornis worm was photographed in Arrábida Natural Park, Portugal.

Salisbury Cathedral is a Church of England cathedral in the city of Salisbury in Wiltshire, England. It was built between 1220 and 1258 in Early English Gothic style. This photograph, taken in 2014, shows the interior of Salisbury Cathedral, looking eastwards towards the high altar through the tall and narrow nave. It has three levels: a tall pointed arcade, an open gallery, and a small clerestory. The nave includes an unconventional modern baptismal font, installed in September 2008. Designed by the water sculptor William Pye, it is the largest working font in any British cathedral. The font is cruciform in shape, and has a 10-foot-wide (3.0 m) vessel filled to its brim with water, designed so that the water overflows in filaments through each corner into bronze gratings embedded in the cathedral's stone floor.

Horatius Cocles was an officer in the army of the early Roman Republic who famously defended the Pons Sublicius from the invading army of Etruscan king Lars Porsena of Clusium in the late 6th century BC, during the war between Rome and Clusium. By defending the narrow end of the bridge, he and his companions were able to hold off the attacking army long enough to allow other Romans to destroy the bridge behind him, blocking the Etruscans' advance and saving the city. This fanciful engraving of Cocles was produced in 1586 by the German-born Dutch printmaker Hendrick Goltzius. The full-length portrait shows him holding a raised sword in his right hand and a shield in his left. In the lower right of the background, Cocles takes on an army by himself.
