il cerchio più piccolo, centrato su un punto del deferente, è l'epiciclo (il suo centro è evidenziato con un punto nero nel disegno, ma ad esso non corrispondeva alcun punto fisico nelle concezioni astronomiche degli antichi); il cerchio rosso pieno è il pianeta, che è centrato su un punto dell'epiciclo; la linea nera spessa rappresenta il moto effettivo del pianeta, che risulta dalla composizione della doppia rivoluzione del deferente intorno alla Terra e dell'epiciclo intorno a un punto del deferente; i punti rossi vuoti rappresentano le successive posizioni del pianeta: visto dalla Terra, esso sembra muoversi in avanti (in direzione est) da 1 a 2, fermarsi in 2, muoversi di moto retrogrado da 2 a 3, fermarsi di nuovo in 3 e poi riprendere il suo moto normale.

the deferent is the epicycle (its center is highlighted with a black dot in the drawing, but it was no physical body according to ancient astronomers); the filled red dot is the planet, which is centered on a point of the epicycle; the bold black line represents the actual motion of the planet, resulting from the composition of the double revolution of the deferent around the Earth and of the epicycle around a point of the deferent; the empty red dots are consecutive positions of the planet. As seen from the Earth, the planet seems to move forward (eastbound) from 1 to 2, to stop in 2, to move backwards from 2 to 3, to stop again in 3 and then to resume its normal forward motion.

model as it was used by
Apollonius, Hipparcus, Ptolemy and others in order to explain the apparent retrograde motion of planets in a geocentric model. The small circle in the center represents the Earth; the larger circle centered on the Earth is the deferent; the smaller circle centerd on a point of

qualitativo. Modelli di questo tipo vennero impiegati da
Apollionio, Ipparco, Tolomeo e altri per spiegare i moti retrogradi apparenti dei pianeti nei sistemi astronomici geocentrici. Il piccolo cerchio vuoto al centro rappresenta la Terra; il cerchio più ampio, centrato nella Terra, è il deferente;
