Animation 3.1: Conjunction and Revolution – 5:3 Ratio of Rotational Speeds.  This animation shows how a 5:3 ratio of motions will return to the initial conjunction.  Oresme's writes, "When A will have made 5 circulations, B will have made 3, and they will be where they are now."


Animation 3.2: 15 Day Revolution. Conjunction at 7.5 days is indicated.

Animation 3.5: Proximate Conjunction [the same as Anim. 3.2]


Animation 3.6: Spatial and Temporal Distribution of Conjunctions for 12:5 Ratio of Motions.


Animation 3.7: Conjunctions for a 2:1 Ratio of Orbital Speeds.

The Stranger Side of Quadrivial Pursuits


Look about 3/5 down this site for the description of the Monochord Table.

This 55-stringed "monochord" is astronomically tuned ["tuned according to the season of the year"].  Lie down on this monochord table, relax, and get a tune-up.  The sound file is is nifty.

If you prefer, you could have the monochord lie on you.
