In medieval medicine, urine was one of the main tools for diagnosis. Physicians studied its colour, from pale to cabbage green, and its thickness, from watery to coarse like meal, and matched these to a chart of the four bodily humours. The practice, called uroscopy, was used to identify disease, but it could also be used to guess a patient's sexual history, the likelihood of recovery and even impending death. Manuscripts and illustrated charts show how detailed the classifications became. Uroscopy was a method that looked convincing on paper, because it turned a bottle of liquid into a readable record of the body's inner state. It was common enough that the flask became a symbol of the physician.

Israeli reports also say the cabinet directed the military to prepare for a possible new attack on Iran.

Angkor, near Siem Reap in northern Cambodia, was the capital of the Khmer Empire, which ruled much of mainland Southeast Asia between roughly the 9th and 15th centuries. At its height the city spread across about 3,000 square kilometres, making it the largest pre-industrial city on Earth by area. Its growth depended on water: huge reservoirs called barays, along with canals and embankments, stored monsoon rain and carried it to rice fields. That system let farmers harvest more than once a year and fed a very large population through the dry season. The temple complex of Angkor Wat, built in the early 12th century, is the best-known monument and still stands at the heart of the park.
