Chronology of Ancient Philosophers

The following list includes all of the more significant ancient philosophers. Rather than attempt to produce extended glosses for every name, instead I have included links to entries in the Internet Encyclopedia of Philosophy. These have been supplemented with links to the McTutor History of Mathematics which also includes a number of useful entires. Dates generally follow those in the OCD, may not correspond exactly to those cited in linked articles, and in many cases are uncertain.
