[finer] particles into the air. But those parts even thicker than these,
having been carried upward to a certain degree or to some extent because of the
continuity of the region, return again to the lower place to
join with the earthy elements. Nor is it the case that water does not change into air
when it is consumed by fire. For the vapors atmoi original: "ἀτμοί" (atmoi). Heron uses this to describe steam or gaseous discharge from heated liquids. from underlying
cauldrons are nothing other than the particles of the liquid, being thinned,
passing into the air. That fire dissolves
all things thicker than itself and transforms them is
clear from this. And from the exhalations anathymiaseōn original: "ἀναθυμιάσεων" (anathymiaseōn). A classical scientific term for vapors rising from the earth or sea, often thought to produce wind, rain, or minerals. occurring from the earth,
it transforms certain thicker bodies
into finer substances. For dews drosoi original: "δρόσοι" (drosoi). differ in no other
way than by the water in the earth being thinned by
some exhalation. This exhalation is produced by a certain
fiery substance while the sun hēlios original: "ἥλιος" (hēlios). is beneath the earth, warming
that region—especially when the soil is sulfurous theiōdē original: "θειώδη" (theiōdē). Related to sulfur, which was known for its combustible and heat-producing properties. or bituminous asphaltōdē original: "ἀσφαλτώδη" (asphaltōdē). Referring to bitumen, a naturally occurring petroleum substance.;
being warmed, it creates an abundance of
exhalations. And the hot springs therma tōn hydatōn original: "θερμὰ τῶν ὑδάτων" (literally "the hot [parts] of the waters").
found in the earth arise from this same cause. Thus, of
these substances, the finer parts change into air, while the
thicker parts, having been carried upward to a certain degree, through the same ex[halation]...
