NEW YORK - They were more than mere kings: They were gods.

For the ancient Maya, living in what is present-day southern Mexico, Guatemala, Honduras and Belize, their rulers were the ones who ensured order in the cosmos, who embodied the divine and carried out rituals so that their people would prosper.

The craftsmanship of the period reflected that reality, a new exhibition shows. "Treasures of Sacred Maya Kings" opens Tuesday at the Metropolitan Museum of Art and runs through Sept. 10. The show features more than 150 objects primarily from Guatemala, Mexico and Honduras, some recently excavated, that highlight the connection.

"We don't have separation of church and state" among the Maya, said Virginia Fields of the Los Angeles County Museum of Art, who originally curated the show. "It's very much the involvement of supernatural forces and ancestors in maintaining the well-being of the community, and the king is the one who is the intermediary between these supernatural beings and the human community."

Maya rulers would wear costumes and vestments that invoked the gods, such as a crown in the show that features an image of maize, the main crop, to show that the wearer had the power of the maize god and could bring a good harvest. They took part in rituals, like bloodletting or imbibing hallucinogens, that were meant to connect them with their ancestors and with supernatural spirits for the good of the people. Even those objects used in the rituals, such as bowls or instruments to draw blood, were decorated with symbols to show the divine connection.

The show, organized in thematic sections on such subjects as religious duties, royal portraits, writing and royal feasting, emphasizes a time period from about 200 B.C. to 600 A.D. The era was a high point for the Maya, Fields said. "This is really where a lot of these ideas came together," she said. "This is really where it all began."

The exhibit has already been seen in Los Angeles and Dallas. The museum plans a range of programming to complement the exhibition.

Julie Jones, who organized the show at the Met, said she hoped visitors would come away with an appreciation for the creativity and culture of the Maya.

"They were great artists _ imaginative, inventive, intellectual and it all shows up in their works of art," she said.
