He was accused of impiety by the comic poet Cratinus in his Panoptae , and , according to Clement of Alexandria , Hippo supposedly ordered the following couplet to be inscribed on his tomb : Behold the tomb of Hippo , whom in death Fate made an equal of the immortal gods . According to Hippolytus , Hippo held water and fire to be the primary elements , with fire originating from water , and then developing itself by generating the universe . Simplicius , too , says that Hippo thought that water was the principle of all things . Most of the accounts of his philosophy suggest that he was interested in biological matters . He thought that there is an appropriate level of moisture in all living things , and disease is caused when the moisture is out of balance .
