the history or description of the chaos. See Chaos.

Orpheus, in his chaology, sets forth the different alterations, secretions, and diverse forms, which matter went through till it became inhabitable, which amounts to the same with what we otherwise call cosmogony. Dr Burnet, in his theory of the earth, represents the chaos as it was at first, entire, undivided, and universally rude and deformed; or the tohu bohu; then shows how it came to be divided into its respective regions; how the homogeneous matter gathered itself apart from all of a contrary principle; and lastly, how it hardened and became a solid habitable globe. See Earth.
