A clutch of complaints by U.S. viewers that the Athens Olympics opening ceremony featured lewd nudity has incensed the Games chief, who warned American regulators to back off from policing ancient Greek culture.

Gianna Angelopoulos warned the Federal Communications Commission watchdog, sensitive after a deluge of outrage when singer Janet Jackson's [Images] breast was exposed at a Super Bowl game, not to punish NBC television that aired the Games.

Male nudity, a woman's breast and simulated sex were the subjects of shrill complaints about the opening ceremony on Aug. 13 which were posted by the FCC on its Web site.

"Far from being indecent, the opening ceremonies were beautiful, enlightening, uplifting and enjoyable," Angelopoulos wrote in a weekend commentary in the Los Angeles Times titled "Since When is Greece's Culture Obscene?"

"Greece does not wish to be drawn into an American culture war. Yet that is exactly what is happening," she said.

Complaints focused on a parade of actors portraying naked statues. Among them were the Satyr and the nude Kouros male statues, both emblems of ancient Greece's golden age.

Created by modern Greek dancer Dimitris Papaioannou and broadcast in the United States by NBC, the opening ceremony was credited with giving the Games a vitally successful start.

HISTORY OF EROS

"We also showed a couple enjoying their love of the Greek sea and each other. And we told the history of Eros, the god of love. Turning love, yearning and desire into a deity is an important part of our contribution to civilisation," Angelopoulos said.

The FCC, whose authority only extends to U.S. media, has said it is looking into complaints, nine of which were listed on its Web site, but it was not clear whether a formal investigation would be launched.

Angelopoulos, who said the handful of U.S. complaints were dwarfed by the 3.9 billion people who watched the ceremony, had a blunt message.

"As Americans surely are aware, there is great hostility in the world today to cultural domination in which a single value system created elsewhere diminishes and degrades local cultures," she said in her commentary.

"In this context, it is astonishingly unwise for an agency of the U.S. government to engage in an investigation that could label a presentation of the Greek origins of civilisation as unfit for television viewing."

An FCC spokesman was not immediately available for comment on Monday, which is a public holiday in America.
