Here’s how the items relate to either Aristotle's model, Ptolemy's model, or both:
**Aristotle's Model:**
- planets fixed on nested spheres
- geocentric
**Ptolemy's Model:**
- Planets fixed on epicycles
- accurately predicted the positions of the planets
- geocentric (also applies to Aristotle’s model)
So, both Aristotle and Ptolemy share the geocentric view of the universe, but the other items are specific to their models.
