Hey Brady/Louisiane -- charts such as your "mystery page" from the Schoener book have been discussed in a paper: "Experimenting with Paper Instruments in Fifteenth-and Sixteenth-Century Astronomy: Computing Syzygies with Isotemporal Lines and Salt Dishes" by Richard L. Kremer out of Darmouth College.

7:43 I think it's most likely a hand-operated ballast tank. Crank on the handle to alternately compress or expand the air in the chamber to change its density which will cause the diver to sink or rise.

@jiroscop 2 года назад

Wow, that's amazing. Yep, I agree it should be a balast tank

@geocider22 Год назад

I thought it was a pump for the air-supply, and they just neglected to draw the connections, but a ballast tank does seem more likely.

That saw was actually a rack and pinion gear which moves the piston in and out when the handle is turned.

@Nilguiri 2 года назад

It is obviously an air compressor to pressurise the air in the "breathing bag" so that it is equalised with the pressure underwater at that depth. Nowadays we used a compressed air tank coupled with a regulator.

What an honor to handle paper that's more than 500 years old! I really appreciate the work of the Royal Society in conserving these documents. The earliest days of the printing press can still be viewed today; whereas the earliest days of the internet have already vanished in time. Great video! Keep up the good work, Brady! :)

@PopeLando 2 года назад

The Almanac is so old they haven't finalised the form of the so-called "Arabic" numerals for 4, 5 and 7, but there's the 0 as plain as day. 1st column on the right might be lunar dates and they go from 0 to 29. A surprising absence of any Roman numerals, in fact. First column: our conventional date of the month, 1, 2, 3 etc Second column, the Dominical Letter, you used to tell when Sunday was each year Third Column: the date in Roman form counting down successively to the Nones and the Ides of this month and then down to the Kalends of next month. Fourth column: Saints' days etc Fifth column: lunar date, seemingly correct for 1472 (new moon on Jan 11). On the left page the columns are labelled 1475, 1494 and 1513.

@grahamrich9956 2 года назад

@PopeLando 2 года назад

@@grahamrich9956 Because a) a lot of people seem to pile on when you call them Arabic numerals because their origin is actually Indian and b) the numerals used by Arabs today are different again. The numbers used in the Western world are called "Arabic" but how do you then differentiate them from actual Arabic numbers?

@grahamrich9956 2 года назад

@jared_bowden 2 года назад

The numerals can be seen well at 2:46 - great detail that I hadn't noticed at first. The 4 looks like a simple loop (like the top half of an 8), the 5 looks like a flipped question mark (kinda like ʕ) or like a 4 without the second bar, and the 7 is rotated so that is looks like lambda (Λ).

6:27 you can clearly see that this is the visible side of the moon. they would have had no way of knowing what the other side could possibly look like mare serentatis, crisium and tranquilitatis are very easy to spot. same with the 2 obvious rays coming from Tycho crater and Copernicus and Kepler craters

I thought the mechanical item on the underwater bag was an air pump as it has a ratchet and piston. There has to be some way to get the air from the surface and dispel old air. Also on that page there is a drawing of a strange little submarine with air bags for breathing and a big straw attached to one's head that would allow breathing underwater. I doubt that the oars for propulsion would work underwater but still fascinating. Strange stuff indeed but imaginations of a future to come centuries later.

@PatricksRareBooks 2 года назад

Forensic pathologist, medical historian, and rare book dealer here. These are anatomies, not autopsies. The two are (and have always been) very different. It is also worth noting that the notion that dissection was taboo at this point in history is little more than myth. Human dissection had grown quite wide-spread across Europe by the early 17th century. The demon over Eve’s genitalia strikes me more as a reminder to the reader not to lust, rather than a warning about what you will see (but others may disagree).

@RFC-3514 2 года назад

Well, for a certain value of "widespread". That's how they got the material to make the drawings in the first place, of course. But I think the point was they were frowned upon by the church (and some of its followers), hence the idea to dress it up as a "church-approved" anatomy book.

Just a slight refinement of the transcription of the Latin at 5:17 AEQVATORIVM CONIVNCTIONVM, OPPOSITIONVM ATQUE ASPECTVVM LVNE AD SOLEM. The V is just the same as U. All the words that end (i)vm are in the genitive plural. I think it's a list, so you would expect a comma after AEQVATORIVM, but pre-modern punctuation is very inconsistent, so I think aequator is a noun, rather than an adjective (I can't find aequat- as an adjective in the dictionary of later Latin I've got). I don't know about astronomy, so there's a chance of error from that cause (would "of equatorial conjunctions" make sense, astronomically?), but I would translate: "Of (the) equators, conjunctions, oppositions and aspects of the moon towards the sun."
