The Nemean Games (Greek: Νέμεα or Νέμεια) were one of the four Panhellenic Games of Ancient Greece, and were held at Nemea every two years (or every third).
Theorodokoi (Greek: θεωροδόκοι or θεαροδόκοι ) in Ancient Greece were sacred envoy-receivers, whose duty was to host and assist the Theoroi ("θεωροί") "viewers" before Panhellenic Games and Festivals.
 Theorodokos was sometimes appointed by the community in which he lived but sometimes by the community that sent out the Theoroi.
Isthmian Games or Isthmia (Ancient Greek: Ἴσθμια) were one of the Panhellenic Games of Ancient Greece, and were named after the Isthmus of Corinth, where they were held.
 As with the Nemean Games, the Isthmian Games were held both the year before and the year after the Olympic Games (the second and fourth years of an Olympiad), while the Pythian Games were held in the third year of the Olympiad cycle.
Kleitomachos (Greek: Κλειτόμαχος, variously also transliterated Cleitomachus or Clitomachus) was a Theban athlete considered a formidable boxer.
 His achievements were recounted by Pausanias, who notes that he won the boxing and pankration at the 141st Olympiad in 216 BC, the pankration at three Pythian Games, and the wrestling, boxing, and pankration at an Isthmian Games.
 This latter achievement, victory in all three so-called "downing" events, was regarded as especially impressive, and was only achieved by one other athlete (Theagenes of Thasos).
 Aelian praised Kleitomachos for his temperance, holding it to be the key to his athletic prowess.
 In particular, he noted Kleitomachos' abstinence from sex, saying that he would even avert his eyes if he saw two dogs coupling.
Panhellenic Games is the collective term for four separate sports festivals held in ancient Greece.
 The four Games were:
The epinikion or epinicion (plural "epinikia" or "epinicia", Greek ἐπινίκιον , from "epi-", "on," + "nikê", "victory") is a genre of occasional poetry also known in English as a victory ode.
 In ancient Greece, the "epinikion" most often took the form of a choral lyric, commissioned for and performed at the celebration of an athletic victory in the Panhellenic Games and sometimes in honor of a victory in war.
 Major poets in the genre are Simonides, Bacchylides, and Pindar.
The Pythian Games (Greek: Πύθια ; also Delphic Games) were one of the four Panhellenic Games of Ancient Greece.
 They were held in honour of Apollo every four years at his sanctuary at Delphi.
 They were held two years after each Olympic Games, and between each Nemean and Isthmian Games.
 The Pythian Games were founded sometime in the 6th century BC, and, unlike the Olympic Games, also featured competitions for art and dance.
 The art and dance competitions pre-dated the athletic portion of the games, and were said to have been started by Apollo after he killed Python and set up the oracle at Delphi.
 Otherwise, the athletic events were the same as those at the Olympic Games.
Black Athena: The Afroasiatic Roots of Classical Civilization, its three volumes first published in 1987, 1991, and 2006 respectively, is a controversial scholarly work by Martin Bernal.
 He discusses ancient Greece in a new light.
 Bernal's thesis discusses the perception of ancient Greece in relation to Greece's African and Asiatic neighbors, especially the ancient Egyptians and Phoenicians who, he believes, colonized ancient Greece.
The Ancient Olympic pentathlon () was an athletic contest at the Ancient Olympic Games, and other Panhellenic Games of Ancient Greece.
 The name derives from Greek, combining the words "pente" (five) and "athlon" (competition).
 Five events were contested over one day, starting with the "stadion" (a short foot race) followed by the Javelin throw, Discus throw, Long jump (the order of these three events is still unclear), and ending with wrestling.
 While Pentathletes were considered to be inferior to the specialized athletes in a certain event, they were superior in overall development and were some of the most well balanced of all the athletes.
 Their training was often part of military service—each of the five events was thought to be useful in battle.
The Olympic Games was originally meant as a festival, or celebration of/for Zeus; later, events such as a footrace, a javelin contest, and wrestling matches were added.
 The Olympic Games (Ancient Greek: Ὀλύμπια "Olympia" "the Olympics" also Ancient Greek: Ὀλυμπιάς "Olympias" "the Olympiad") were a series of athletic competitions among representatives of city-states and one of the Panhellenic Games of ancient Greece.
 They were held in honor of Zeus, and the Greeks gave them a mythological origin.
 The first Olympics is traditionally dated to 776 BC.
 They continued to be celebrated when Greece came under Roman rule, until the emperor Theodosius I suppressed them in 393 AD as part of the campaign to impose Christianity as the State religion of Rome.
 The games were held every four years, or "olympiad", which became a unit of time in historical chronologies.
