Is Buddhist Cosmology part of the early discourses ?

Question

Where might I find commentary on cosmology in the Suttas?

Answer 1

In the book I referred to in an earlier post Punnadhammo Mahāthero points to suttas as well as commentaries of Theravāda and Sarvāstivāda.

Therefore, my answer would be: yes. Buddhist Cosmology is part of the early discourses.
