Jacob of Sarug's Homilies on the Six Days of Creation: The Second Day by Edward G Mathews Jr
In this second part of Homily 71, On the Fashioning of Creation, Jacob treats the making of the firmament: what it was, where it was, what - as far as can be determined - was placed above it and what below it, its purpose and utility for humanity, and the importance of its place in the Genesis account of the six day progression of creation.
