  • In ancient times, people did not have the concept of a “civil day”; they viewed day and night as separate things which alternated.

    The Assyrians divided the day into six equal parts, and the night into six equal parts, called ush. But because sunrise and sunset move around over the course of the year, the lengths of day and night vary, and thus one ush during the day would not be the same length as an ush at night except around the equinoxes.

    The Babylonians divided ushes in two to make hours, because it was easier to do astronomy in 12s than 6es. This resulted in 12 hours in a day and 12 hours at night, but daytime hours were still different lengths to nighttime hours, and the lengths of hours still varied over the course of the year.

    The Greeks partially adopted the Babylonian system; they divided the day into 12 hours but the night was divided into four watches. The Romans copied the Greek system, but later went full Babylonian with 12 hours at night as well. (I feel like this coïncided with the rise of Christianity, but I have no evidence). The Romans introduced the concept of the civil day beginning at midnight (which the Chinese independently came up with), and over time, this led to the idea of 12 hours from midnight to noon, and 12 hours from noon to midnight. That idea postdates Rome, however; Roman hours were reckoned from sunrise to sunset and sunset to sunrise.

    Assyrian astronomical knowledge seems to have reached China via India, as traditional Chinese timekeeping divides the civil day into 12 shi. Ancient shi were like Assyrian ushes; they were either 1/6 of a day or 1/6 of a night. Originally, midnight and noon fell in the middle of a shi, but this was changed to shi starting at midnight to make administration and astronomy easier. This system of variable-length shi continued to be used in Japan until about the Meiji Restoration.

    Fixed-length hours are the result of analogue clocks, which are impractical to design to change the lengths of hours with the seasons (but not impossible; the wskusei clock is an ingenious Japanese clock from the 17th century that does exactly that). China had reliable, accurate water clocks by the Tang dynasty, while Europeans developed circular mechsnical clocks in the late Middle Ages. In neither case was it practical to make something as clever as the wakusei clock, so analogue clocks were marked the mean length of a shi or an hour as a reasonable approximation. Since there are 12 hours from midnight to noon and 12 from noon to midnight, that led to the 12-hour time system we know today.


  • Oh it gets better.

    The statue — which rises 15 feet atop a 7-foot base — was commissioned and bankrolled by a collective of crypto investors seeking to boost visibility for their memecoin, $PATRIOT, according to The Daily Beast.

    Sculptor Alan Cottrill told The Times in February that he agreed to create the bronze figure for $300,000 but complained that the investors were slow in paying. In November he proposed coating it in gold leaf.

    His suggestion went down like an offering of water “to a person dying of thirst,” he said. “Immediately everybody jumped on board.”











  • I’m reading The Ottomans: Khans, Caesars, and Caliphs by Marc David Baer. One of the numerous things he talks about is attitudes to wine in the Ottoman court, which set the time for all of contemporary Türkiye. Baer compares Turkish attitudes toward wine with similarly positive attitudes in Iran and the Arab nations, also noting that the Ottomans and Safavids both condemned each other as being drunk as good Muslims must never be. (The Ottomans and Safabids were constantly calling each other blasphemous for indulging in the very things they themselves loved doing).
