Science were laid during the peak of Ionic philosophy during the 5th and 6th century BC. From the 5th and 6th century BC medicine was taught at philosophical centres like Knidos and Kos. Knido was located on the Asia Minor coast close to Kos. Relations between Kos and Knido were close as both were members of the Doric sixcity Alliance. The Medical School of Knidos may have been older and paid more attention to researching the symptoms of every illness. As therapy they used to tried and tested traditional methods. At the school in Kos doctors examined the disease, taking into consideration the whole situation and looking for ways not only to cure it but to prevent it as well.
