Medieval (g)astronomy: my PhD in biscuit form
Updated: May 13, 2020
I submitted my PhD thesis last week (and now have a little more time to post on this blog). In large part it’s a study of this fascinating instrument.
But until now, I’d never made an edible equatorium.
It was a bit tricky to get everything the right shape, and the gingerbread expanded more than I had expected in the oven, but it all came out pretty well…
Add a screw and nut to hold the rule to the epicycle, position them correctly, and here’s your complete equatorium!
