Statue of Zeus at Olympia in the context of "Ancient Olympic Games"

Phidias or Pheidias (/ˈfɪdiəs/; Ancient Greek: Φειδίας, Pheidias; c. 480 – c. 430 BC) was an Ancient Greek sculptor, painter, and architect, active in the 5th century BC. His Statue of Zeus at Olympia was one of the Seven Wonders of the Ancient World. Phidias also designed the statues of the goddess Athena on the Athenian Acropolis, namely the Athena Parthenos inside the Parthenon, and the Athena Promachos, a colossal bronze which stood between it and the Propylaea, a monumental gateway that served as the entrance to the Acropolis in Athens. Phidias was the son of Charmides of Athens. The ancients believed that his masters were Hegias and Ageladas.

Plutarch discusses Phidias's friendship with the Greek statesman Pericles, recording that enemies of Pericles tried to attack him through Phidias – who was accused of stealing gold intended for the Parthenon's statue of Athena, and of impiously portraying himself and Pericles on the shield of the statue. The historical value of this account, as well as the legend about accusations against the 'Periclean circle', is debatable, but Aristophanes mentions an incident with Phidias around that time.

The Seven Wonders of the Ancient World, also known as the Seven Wonders of the World or simply the Seven Wonders, is a list of seven notable structures present during classical antiquity, first established in the 1572 publication Octo Mundi Miracula using a combination of historical sources.

The seven traditional wonders established by the Octo Mundi Miracula are the Great Pyramid of Giza, the Colossus of Rhodes, the Lighthouse of Alexandria, the Mausoleum at Halicarnassus, the Temple of Artemis, the Statue of Zeus at Olympia, and the Hanging Gardens of Babylon. Using modern-day countries, two of the wonders were located in Greece, two in Turkey, two in Egypt, and one in Iraq. Of the seven wonders, only the Pyramid of Giza, which is also by far the oldest of the wonders, remains standing, while the others have been destroyed over the centuries. Remains exist from the Lighthouse, Temple of Artemis and the Mausoleum – either in situ or in museums. There is scholarly debate over the exact nature of the Hanging Gardens, and there is doubt as to whether they existed at all.

Various lists of the Wonders of the World have been compiled from antiquity to the present day, in order to catalogue the world's most spectacular natural features and human-built structures.

The Seven Wonders of the Ancient World is the oldest known list of this type, documenting the most iconic and remarkable human-made creations of classical antiquity; the canonical list was established in the 1572 Octo Mundi Miracula, based on classical sources which varied widely. The classical sources only include works located around the Mediterranean rim and in the ancient Near East. The number seven was chosen because the Greeks believed it represented perfection and plenty, and because it reflected the number of planets known in ancient times (five) plus the Sun and Moon.
