Epicycle calculations. 16th-century calculations of epicycle motions of an astronomical body. Epicycles were mathematical constructs used to explain geocentric orbits before heliocentric models simplified the calculations. This set of calculations starts in 1580 (labelled at right) and finishes in 1596 (labelled at left). An example of such a calculation was the orbit of the planet Mars as seen from Earth. This diagram is from 'Sphaera mundi' (1635) by Italian Jesuit astronomer and mathematician Giuseppe Biancani (1566-1624) | |
