The seven-day week has no correspondence to astronomy -- unlike the presence of the sun giving us days, or phases of the moon giving us months. Historians generally think the seven-day week was "invented" by Mesopotamians and/or Jews. Both thought the number seven had mystic significance. Sumer had a (mostly) seven-day week system since at least the 21st century BCE. The Jewish weeks may have developed independently or been influenced by their Fertile Crescent neighbors.
From the crossroads of Europe, Asia, and Africa the seven-day week spread around the Old World. The Greeks and Persians adopted the Babylonian system, and fro Persia it spread to India and China in various forms. In Japan, for instance, seven-day weeks were mainly used by specialist astrologers until the 1800s. In Europe, it was officially adopted by the Roman Empire in the 300s CE, but it was already in common use throughout the empire.
In 1932, pilot George Palmer was flying from Las Vegas to Blythe, Calif., when he saw drawings sketched on the desert. Someone had scraped away the dark surface soil to draw three human figures, two four-legged animals, and a spiral.
Like the more famous Nazca Lines in Peru, the Blythe Intaglios had gone unnoticed for so long because they were too big! The largest is over 170 feet long. Much too big to be seen from the ground. No local Native American group claims to have made them; radiocarbon dating places their creation between 900 BCE and 1200 CE.
The Aztecs and Mayans feared and hated the owl and believed they were symbols of death and destruction. Interestingly, the Romans agreed, believing that the owls were bad omens -- but the ancient Greeks did not. In ancient Greece, owls represented Athena, the goddess of wisdom.
Watch the whole thing, its fascinating!
Greenland's icy mountains are not an obvious place to search for an archive of economic history, but a study just published in the Proceedings of the National Academy of Sciences shows that they provide one. Read the full article at The Economist
The ruined city of Arg-e-Bam is made entirely of mud bricks, clay, straw and the trunks of palm trees. The Iranian city was originally founded during the Sassanian period (224-637 CE) and while some of the surviving structures date from before the 1100s, most of what remains was built during the Safavid period (1502-1722). Bam prospered because of pilgrims visiting its Zoroastrian fire temple, which had been built early in the Sassanian period, and because Bam was a trading hub along the Silk Road. It was later the site of Jame Mosque, built during the Saffarian period (866-903 CE). Next to the mosque is the tomb of Mirza Naiim, a mystic and astronomer. The city was largely abandoned since a series of invasions in the early 1800s. In 1953, work began to intensively restore Arg-e-Bam. Restoration work continued until December 26, 2003, when a massive earthquake hit the area -- an estimated 6.6 on the Richter Scale. Almost everything in Bam was destroyed. After that, restoration was given up, and today Arg-e-Bam is at the mercy of the elements. click through the image gallery to see photographs of what Arg-e-Bam looks like today
This blog is a collection of the interesting, the weird, and sometimes the need-to-know about history, culled from around the internet.
