firmament mid-13c., from L. firmamentum "firmament," lit. "a support or strengthening," from firmus "firm" (see firm (adj.)), used in Vulgate to translate Gk. stereoma "firm or solid structure," which translated Heb. raqia, a word used of both the vault of the sky and the floor of the earth in the O.T., probably lit. "expanse," from raqa "to spread out," but in Syriac meaning "to make firm or solid," hence the erroneous translation.
