<P> A Greek text called the Kore Kosmou ("Virgin of the World") ascribed to Hermes Trismegistus (associated with the Egyptian god Thoth), names the four elements fire, water, air, and earth . As described in this book: </P> <P> And Isis answer made: Of living things, my son, some are made friends with fire, and some with water, some with air, and some with earth, and some with two or three of these, and some with all . And, on the contrary, again some are made enemies of fire, and some of water, some of earth, and some of air, and some of two of them, and some of three, and some of all . For instance, son, the locust and all flies flee fire; the eagle and the hawk and all high - flying birds flee water; fish, air and earth; the snake avoids the open air . Whereas snakes and all creeping things love earth; all swimming things love water; winged things, air, of which they are the citizens; while those that fly still higher love the fire and have the habitat near it . Not that some of the animals as well do not love fire; for instance salamanders, for they even have their homes in it . It is because one or another of the elements doth form their bodies' outer envelope . Each soul, accordingly, while it is in its body is weighted and constricted by these four . </P> <P> According to Galen, these elements were used by Hippocrates in describing the human body with an association with the four humours: yellow bile (fire), black bile (earth), blood (air), and phlegm (water). Medical care was flexible and primarily about helping the patient stay in or return to his / her own personal natural balanced state . </P> <P> In Babylonian mythology, the cosmogony called Enûma Eliš, a text written between the 18th and 16th centuries BC, involves four gods that we might see as personified cosmic elements: sea, earth, sky, wind . In other Babylonian texts these phenomena are considered independent of their association with deities, though they are not treated as the component elements of the universe, as later in Empedocles . </P>
