imgur.com/a/QJjm1z7You found Venus on Atalanta Fugiens and I used it to find Mars. Also I trigged the whole idea out. 23.5 has no legs because of constraints: the compass point rests on the "Equator" and the "Mercury" box has to be a square. Only one angle can tick that box and I found it - largely by trial-an-error - and that led to me writing the proof (by null hypothesis). The angle is 22.546. Once you know all this you can put all the trig. in your back pocket and move across to 22.5 and classical geometry - compass, rule and pencil. If you start with the Earth square and draw in the planet circumference (scale 1 : 720 fot 7920 "canonical"). You then first create 45 degrees and then 22.5 in the Moon box. This finds the Atalanta triangle which in turn finds your Venus. It also finds you the "Mercury" square. Surprised you missed this: given Venus you get Mars because 1/2 Venus + Mars pretty much = Earth 9 there's about 50 miles in it over nearly 8000. That's getting on for the thickness of the pencil line for the circumference of Mars. geoff simmons geoffss@aol.com
