Iulis was the birthplace of the lyric poets Simonides and Bacchylides, the philosophers Prodicus and Ariston, and the physician Erasistratus; the excellence of its laws was so generally recognized that the title of Cean Laws passed into a proverb.
Erasistratus, instead of following Hippocrates as Herophilus did, depreciated him, and seems to have been rather aggressive and independent in his views.
The two schools composed of the followers of Herophilus and Erasistratus respectively long divided between them the medical world of Alexandria.
The school of Erasistratus was less distinguished in anatomy than that of Herophilus, but paid more attention to the special symptoms of diseases, and employed a great variety of drugs.
He wrote several philosophical dialogues: (I) Concerning virtue, whether it can be taught; (2) Eryxias, or Erasistratus; concerning riches, whether they are good; (3) Axiochus: concerning death, whether it is to be feared, - but those extant on the several subjects are not genuine remains.
The science of medicine had distinguished representatives in Herophilus and Erasistratus, the two first great anatomists.
A generation afterwards Erasistratus made this the basis of a new theory of diseases and their treatment.
