Athenian Acropolis
An ancient citadel located in the city of Athens containing the remains of several ancient buildings including the Parthenon, the Propylaea, the Erechtheion, and the Temple of Athena Nike.

Pentelic marble
A famous Greek marble quarried at Mount Pentelikon near Athens. It is pure white but may turn yellow after long exposure to air; a few miniscule veins of talc sometimes cause a faint greenish tint. It was used in antiquity as early as the 6th century BCE and continued to be popular for both sculpture and architecture; both the sculptural decoration and the architectural members of the Parthenon are made of Pentelic marble.

Classical
Refers to an ancient Greek style and period that begins around 480 BCE, when the Greek city-states defeated the Persian invaders, and ends around 323 BCE, with the death of Alexander the Great. It is characterized by the rebuilding of cities after the Persian wars, the flourishing of philosophy, drama, architecture, sculpture, painting, and the other arts. In the visual arts, it is known for the mastery of the human form and sophistication of architectural design.

public domain
Land owned and controlled by the state or federal government. Also, the status of publications, products, and processes that are not protected under patent or copyright.

acropolises
The higher and usually fortified sections of ancient Greek cities, typically containing temples and some public buildings and used as places of refuge.

Ancient Greek
Refers to the culture and styles of ancient Greece, generally excluding modern and prehistoric periods, but including periods between around 900 BCE to around 31 BCE. For the culture of Greece in general, including modern Greece, see "Greek."

Parthenon
An ancient temple on the Athenian Acropolis dedicated to the goddess Athena Parthenos during the 5th century BCE. The structure was built to commemorate the Greek victory over the Persians and also served as the city's treasury.

sculpture
Three-dimensional works of art in which images and forms are produced in relief, in intaglio, or in the round. The term refers particularly to art works created by carving or engraving a hard material, by molding or casting a malleable material (which usually then hardens), or by assembling parts to create a three-dimensional object. It is typically used to refer to large or medium-sized objects made of stone, wood, bronze, or another metal. Small objects are typically referred to as "carvings" or another appropriate term. "Sculpture" refers to works that represent tangible beings, objects, or groups of objects, or are abstract works that have defined edges and boundaries and can be measured. As three-dimensional works become more diffused in space or time, or less tangible, use appropriate specific terms, such as "mail art" or "environmental art."
