What are ten artworks you could find in Italy and produced by Italian (or Roman/Etruscan) artists that embody the Greek ideal of art (the piece has to reside in Italy)? How does each piece makes reference to some Greek ideal? (You can include architecture.)
In order to find artworks influenced by the Greek ideals, one can look before the High Renaissance when Italians moved to new art forms all their own. In large part, it was in sculpture, that Roman art was influenced by Grecian works.
1. Allegorical scene from the reign of Augustus Caesar. (13 B.C.) [http://en.wikipedia.org/wiki/Roman_sculpture] This work is in relief in the Greek style in which some of the original material from which the artwork is created is evident; in addition, the work is a very decorative and elaborate scene.
2. A relief entitled Botany, possibly created by Matteo de Pasti demonstrates the influence of 5th century Athenian art.
3. In the 1st century A.D. what was called Patrician Art was influenced by the Hellenistic style . (search "Roman patrician sculpture" for many examples), These were sculptures of rulers and patricians or their families.
4. Trajan's Column in Rome, north of the Roman Forum. (113A.D.) During the time that this column was made, many of the sculptors were Greeks often enslaved after conquests such as that of Corinth. This column is hollow exhibits a spiraling frieze made in the style of the Greeks.
5. Michelangelo's Sistine nudes have clearly been influenced by The Belvedere Torso by Appolonios that is Hellenistic in its energy of musculature. In fact, this sculpture found its way into Rome later on.
6. Augustus, depicted in a toga as an officiating priest (27 A.D.) in a pose derived from Greek prototypes. There are other such sculptures of Augustus in armor, or nude that also evince Greek influence.
7. Gold coins with Nero on them depict him wearing long-curled hair in the Greek fashion, and the face is done in the Hellenistic style.
8. In Pompeii, a room in the "house of the Vetti" before 79 A.D. has murals in decorative schemes that are done in a style typical of murals featured in Greek domestic interiors.
9. The Altar of Augustus (13-09 B.C.) is a relief of unstated, cool majesty that strongly demonstrates the influence of Classical Greek art.
10. Pompey (c.50 B.C.) The head of the ruler is an skillful and subtle blend of native Roman, individual portraiture matched with the Greek tradition of smooth harmony. (Greeks did not sever the head from bodies in sculpture)
