Did ptolemy believe in helio

Answer 1

His theory was geo.

The heliocentric theory is modern and has the Sun at the centre of the solar system with the planets going round it in nearly-circular orbits.

Ptolemy's theory, a geocentric one, had the Earth at the centre, with everything else orbiting round it, but Ptolemy found an ingenious way of accounting for the planets' movements in the sky quite accurately.

Ptolemy's method describes the planets' orbits in terms of a basic circular orbit, called the deferent but what goes round the deferent is a smaller circle, the epicycle, and the planet goes round the epicycle.

It isn't difficult to see that this geometrical construction 'takes out' the Earth's movement round the Sun and explains the planets' movements as we see them from the Earth, while allowing the Earth to be fixed at the centre.
