It has been a time of fear and anxiety for the Danish cartoonists whose caricatures of the Prophet Muhammad a year ago caused an uproar in much of the Islamic world, according to the newspaper editor who commissioned the project.

"The cartoonists had to go into hiding and not appear in public," said Flemming Rose, culture editor of Jyllands-Posten.

"They have been under heavy criticism both from inside the country and outside the country," Rose said, speaking to a luncheon at the Nixon Center, a policy research group.

Rose said he has fared better than the cartoonists even though he was the one who came up with the idea.

"It is true that I have received threats," he said. "I have had a dialogue with the Danish police. I have had to change something in my daily routines in Denmark and have had to involve the police in doing certain things."

But, he added, "It has not changed my life."
