Firmament

An artist's depiction of the early Hebrew conception of the cosmos. The firmament (raqia), Sheol, and Tehom are depicted.

In biblical cosmology, the firmament (Hebrew: רָקִ֫יעַ rāqīa) is the vast solid dome created by God during the Genesis creation narrative to divide the primal sea into upper and lower portions so that the dry land could appear.[1][2]

The concept was adopted into the subsequent Classical/Medieval model of heavenly spheres, but was dropped with advances in astronomy in the 16th and 17th centuries. Today it is known as a synonym for sky or heaven.
