BASEL, Switzerland — No, it does not symbolize the dreaded computer virus. Mounted outside the Basel Museum of Antiquities, the 30-foot-high wooden structure suggests what the mythical Trojan Horse may have looked like.

It draws attention to a unique show on Homer, the Greek poet whose monumental epics have had an impact on Western culture for more than 2,500 years.

The proverbial "horse" makes only a short episode in Homer's powerful narrative that has influenced art from Greek vases painted in 600 B.C. to American abstract expressionism. Literature, too, has been stimulated by Homer's works for more than two millennia.

Proof is provided by 230 exhibits on view at the show titled "Homer, the Myth of Troy in Poetry and Art." Lenders include more than 50 European and American museums. Its artistic director, professor Joachim Latacz, a leading international authority on ancient Greece, hopes that the show will reawaken general interest in the roots of Western civilization.

Latacz deplores what he calls the "growing estrangement" between antiquity and the general public in recent decades. He cites in the show's catalog a poll in a German town in which 15 percent of high school students, when asked what they know about Homer, identified him as the character in the popular TV series "The Simpsons."

On view are magnificent Greek and Roman amphorae and vases depicting dramatic scenes of Homer's two epics. In his "Iliad," containing some 16,000 verses, he describes a short phase of a 10-year Trojan war said to have ended with a Greek victory in the 13th century B.C.

In a 12,000-word sequel, the "Odyssey," Homer tells of a dangerous 10-year journey home of the Greek leader Odysseus to his Kingdom on the island of Ithaca. Odysseus is credited with having cunningly smuggled his soldiers inside the huge hollow wooden horse into the besieged citadel of Troy to destroy it.

Coins, statuettes, fragments of text excerpts on Egyptian papyrus and other artifacts on view also stress the dominant effect of Homer's epics on Western culture since antiquity.

The paintings on display make up only a small fraction of the vast imagery influenced by the ancient poetry. They range from copies of Roman frescoes to canvases by German pop artist Sigmar Polke and by Cy Twombly, a key figure in American abstract expressionism. The catalog lists many others from Rembrandt to Picasso.

In a special room, visitors can see a 2006 video installation by American filmmaker Peter Rose, titled "Odysseus on Ithaca." The 2004 movie "Troy," starring Brad Pitt and Peter O'Toole, is loosely based on Homer's epics.
