Cicero (c. 106–c. 43 B.C.) also made one of the earliest known teleological arguments. In "de Natura Deorum (On the Nature of the Gods)" Cicero stated, "The divine power is to be found in a principle of reason that pervades the whole of nature". He was writing from the cultural background of the Roman religion. In Roman mythology the creator goddess, Gaia was borrowed from Greek mythology. The Romans called her Tellus or Terra.
