Beautiful book. Amazing how these were produced so neatly before the computer age. There's whole collection of books like this on archive.org under "Graphic methods"
Full color. Look at the sticker on the second page, the right edge and the letters make the difference very obvious. The PDF looks extremely compressed.
Might indicate poor support for JPEG2000 in Archive's software? That's what you get when you click the download link for "Original" files. Sadly it's not easily readable that way but at least someone could use them to assemble a better PDF with some cropping, rotation, and white-balance: https://i.imgur.com/IdBujgi.png
Towards the end multiples of 10 become more common - I suspect a lot of the years aren't exact. Also some (1528, 1389) are "when the thing happened" and not "when the text was written"
I have added the Kish tablet so that HN now has a reference to what is probably the oldest known text to date: https://news.ycombinator.com/item?id=39493201 It is dated to around 3500 BC.
Coincidentally I posted a link to an article from 1893 earlier today: On Electric Spark Photographs; Or, Photography of Flying Bullets, etc.
