The veil St. Basil speaks of is the firmament, a tell-tale staple in the geocentric flat earth and otherwise excluded in the globe models, but Basil's statement also reveals his understanding of the typology regarding the veil of the tabernacle and earth being a macrocosm of the house of God as Basil, Cosmas and Severian teach, earth is like a two story house with heaven being the upper story, the firmament dividing as a veil with the earth below that.
