These lists are based on information at the Greek Mythology Link.Our modern knowledge of Greek mythology derives not only from archaic and classical (8th to 4th centuries BC) Greek writers such as Homer, Hesiod, Herodotus, Euripides and Sophocles, but also from later Roman and Greek authors such as Apollodorus, Hyginus, Ovid, Virgil and Pausanias. Greek mythology encompasses tales of the Titans and Olympians, the Trojan War, the exploits of Heracles, and much more.
The names presented here are of course transcribed from the original Greek. There are many different methods for doing Greek transcriptions, with the result that the name you are looking for may be spelled in an unexpected way. Greek κ (kappa) may be represented by the Roman letter K or C; the Greek nominative suffix ος (omicron sigma) may be represented by OS or US. In both cases, the names here use the latter strategy, though searches for either form (eg Clitus or Kleitos) should return the same result.
Note that names from Virgil's Aeneid, an extension of the Greek Trojan War tales reworked into a Roman origin story, are included in the Roman mythology section.
