He is variously described as coming from Rhegium , Metapontum , Samos , and Croton , and it is possible that there was more than one philosopher with this name . Although he was a natural philosopher , Aristotle refused to place him among the other great Pre-Socratic philosophers `` because of the paltriness of his thought . '' At some point Hippo was accused of atheism , but as his works have perished , we can not be certain why . 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 . He also viewed the soul as arising from both mind and water . A medieval scholium on Aristophanes ' The Clouds attributes to Hippo the view that the heavens were like the dome of an oven (  ) covering the Earth ., The Basento (Latin "Casuentus") is a river in the Basilicata region of southern Italy.
