The National Museum of Iraq recorded a history of civilizations that began to flourish in the fertile plains of Mesopotamia more than 7,000 years ago. But once American troops entered Baghdad in sufficient force to topple Saddam Hussein's government this week, it took only 48 hours for the museum to be destroyed, with at least 170,000 artifacts carried away by looters.

The full extent of the disaster that befell the museum came to light only today, as the frenzied looting that swept much of the capital over the previous three days began to ebb.

As fires in a dozen government ministries and agencies began to burn out, and as looters tired of pillaging in the 90-degree heat, museum officials reached the hotels where foreign journalists were staying along the eastern bank of the Tigris River. They brought word of what is likely to be reckoned as one of the greatest cultural disasters in recent Middle Eastern history.

A full accounting of what has been lost may take weeks or months. The museum had been closed during much of the 1990's, and as with many Iraqi institutions, its operations were cloaked in secrecy under Mr. Hussein.

UPDATE: A good counterargument to our applying martial law. Not much of a consolation, but...
