Calculation of the area of a trapezoid by a student from ancient Babylonia.
Three of the sides are labelled with numbers, and the area is written out in the centre in the sexagesimal notation system as 5,3,20 𒐊 𒁹𒁹𒁹 𒌋𒌋 (= 5 and 1/18th, I think)
Possibly a Babylonian approximation of pi reflected in this drawing of a circle with inscribed numbers.
A school tablet with calculations of the areas of squares with the teacher’s neat copy on one side (left) and a student’s slightly messier work on the other (right). Can you spot the number 9 inside the innermost square? 𒑆
This lovely tablet that looks like it’s been folded over and has a few numerical notations.
It may have been a “scratch pad” for calculations on a separate administrative text and maybe reused as a candle holder. Dr Christine Proust has written about it academia.edu/34449978/BM_11…
I have like 2,000 emails to reply to and am procrastinating
“Problem: an excavation. The depth is as much as I squared and 7 cubits. I removed 3 20, the volume. What are the length, width, and depth?”
You know when you have so much to do and you don’t know where to start so you do a thread on Babylonian mathematics instead
A round tablet from the Sargonic period (c2350-2250 BCE) that shows a diagram of a bisected trapezoid, probably a school assignment. The area calculated is 1 “sar”, a surface unit (= 36m²)
Thank you so much to the incredible @gregjenner and his team for having me on "You're Dead to Me" and to @kaekurd for being so hilarious and bringing Gilgamesh the restaurant into my life!
Here’s a thread of some of the stuff referenced in the podcast for those interested
First of all, what even is cuneiform?
It’s a writing system from the ancient Middle East, used to write several languages like Sumerian and Akkadian. Cuneiform signs can stand for whole words or syllables. Here’s a little primer of its evolution sites.utexas.edu/dsb/tokens/the…
What kinds of texts was cuneiform used to write?
Initially, accounting records and lists.
Eventually, literature, astronomy, medicine, maps, architectural plans, omens, letters, contracts, law collections, and more.
Good morning! Ancient Babylonians sometimes paid other people to do their laundry for them.
"The dirty clothes that Shaddinnu has given (me) for cleaning, I will clean the dirty clothes by the 10th day of the month Arahsamna and return them to Shaddinnu"
A handful of clay tablets from Uruk, Babylon, and Borsippa in the middle of the first millennium BCE record contracts for doing laundry.
"Ina-teshi-etir, the washerman...will clean and whiten the whites of the house of Nabû-shumu-ukin", for which he gets paid 1 shekel per year
Akkadian word of the day is zikûtu "laundry" because why not
“Will there be a vaccine in 2020?” is a question I wish I could have asked an ancient Babylonian or Assyrian seer in March to assuage anxiety, manage expectations, or make decisions.
Thread on using the organs of sheep to answer specifically worded questions a long time ago
Nature was a clay tablet to the diviner in ancient Mesopotamia. The gods inscribed signs in astronomical phenomena, animal behaviour, plant life, oil, smoke, human physiology, dreams, and animal exta to be read by diviners.
The liver was sometimes called the tablet of the gods.
There is a fancy word in English for liver divination that took me ~3 years to learn to spell: extispicy.
In ancient Mesopotamia, this was the job of the bārû, "seer" or "diviner". A person trained for a Very Long Time to learn to read signs inscribed on the entrails of sheep
As we begin to bid farewell to NEOWISE, I want to take a moment to remember the comets that found their way into cuneiform tablets thousands of years ago, and the people who may have felt the same sense of wonder some of us did when looking at the night sky this July.
The Akkadian word for comet is ṣallammû, or ṣallummû. It appears in cuneiform texts from ancient Babylonia that record centuries of observed astronomical phenomena.
AFAIK, these "Astronomical Diaries" are the longest-running dataset for such phenomena from the ancient world
“the comet which previously had been seen in the east in the path of Anu in the area of Pleiades and Taurus, to the west…and passed along in the path of Ea”
What survives of the past is things, so it's easy to forget the people behind them whose lives, loves, worries, and wants might not have been so different from ours.
Thread of letters from ancient Mesopotamia as a random reminder of our shared humanity
Work anxiety is nothing new.
In the 7th century BCE, a physician named Nabu-tabni-usur found himself an outcast in the king's court and lamented to his royal patron, "If the king knows a fault committed by me, let the king not keep me alive...I am dying of a broken heart!"
An exorcist named Urad-Gula in the court of king Esarhaddon was "dying of a broken heart" after falling out of favour.
The head exorcist, who was Urad-Gula's father, wrote to the king to ask that the "shattered" scholar be reinstated. A 3,000-year-old diplomatic, fatherly moment
“To turn a man into a woman and a woman into a man are yours, Inana,” reads a 4,000-year-old temple hymn to Inana, the Sumerian goddess of love and war.
Ishtar, the later Mesopotamian goddess of love and war, had gender fluid characterstics. Ashurbanipal’s hymn to Ishtar of Nineveh compares her to the god Ashur.
“Like Ashur she wears a beard and is clothed with brilliance...The crown on her head gleams like the stars”
Gender fluid identity appears throughout Mesopotamian history, like that of the assinnu, a word sometimes written as a combination of the cuneiform signs for “man” and “woman”.
They served as cultic personnel to Ishtar and even as prophets, like one named Šēlebum in Mari
