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.

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.

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.

The only thing I (as a humble armchair investigator) can offer on the mystery chart is that part of the title allegedly translates to "Opposite to the sun" (oppositiuinvm atqve aspectvvm lvne ad solem), and part of the dials/separations are in delineations of 12, perhaps marking months or hours, with other sections delineated to 30 perhaps for days in a month.

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." HTH

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).
