Not central, just suspicious, but... this is 'house' as in astrological house as in the first part of the word 'horoscope', not house like a house you live in.
My background in linguistics consists of a couple chompsky soft-science books and a love of tolkien, but if you actually know something and wanna chat I'd honestly love to dig in on this seriously. DM me.
My pet theory is (circa 10000 BCE) that 'houses' and 'hours' are related words, the 12 hour clock matched the zodiac, each hour/house was 1 Assyrian 'watch' and they had no trouble day or night (constellations at night, sundial during the day), they were easy to build, easy to communicate, easy to understand and efficient.
Then the Egyptians stole the technology (Circa 6000BCE) said '12 hours in a day? I got you bro', fucked it up and it all went downhill from there.
Feel free to quote me in your prize winning scientific paper.
This has been the case since it was possible to pay someone to run from village to village shouting things... It's just more now.
Welcome to the party, beers over there.
