The Hermitage: A Russian Odyssey (Public TV stations -- check local listings for days and times): Three centuries of Russian history are the context for this three-part series, a television presentation of The Christian Science Monitor, focusing on one of the world's greatest museums: the Hermitage in St. Petersburg.
Shot entirely on location, the program offers a survey of the museum's dazzling and varied art -- which includes the world's largest group of Rembrandts -- as well as a tour through the impressive building and a continuing tale of how this extraordinary institution has survived through the years.
The first program, ''Catherine the Great: A Lust for Art,'' includes the founding of the Hermitage. Program 2, ''Tyrants and Heroes: The Nineteenth-Century Czars,'' deals with Russia's 19th century.
Program 3, ''From Czars to Commissars: A Museum Survives,'' takes viewers through two world wars, the Bolshevik revolution, and other topics.
The Emmys (ABC, 8-11 p.m., EDT): Television's big night should be more fun this year. Last time, executives from the other networks refused to attend amid a flap over ABC's exclusive four-year deal to air an event that had been rotating among the networks.
On the upcoming show -- the 46th edition of the awards ceremony -- comedy, along with other diversions, looms large. The long list of celebrity presenters includes Jay Leno, Michael Richards, Jerry Seinfeld, and Garry Shandling. And the broadcast offers a feature looking at the impact of stand-up comedy on the medium.
Some 27 awards will be handed out before the long, glittery evening is over.
