COOPERSTOWN - Frederic Edwin Church knew how to work a 19th century crowd.

When he put a single 10-foot painting of an exotic South American landscape on display in a New York gallery, more than 500 people a day flocked to see it for weeks. In 1859, "The Heart of the Andes" provided a rare glimpse at the faraway lands intriguing explorers of the time.

Reminders of such career highlights were what Church chose for display inside Olana, the intricately designed, Persian-style villa on a hill overlooking the Hudson River he had built in the 1870s.

For the first time, 18 oil paintings from Church's personal collection are leaving the state historic site for a six-city traveling exhibition that opened last month at the Fenimore Art Museum in Cooperstown.

The exhibition will visit the Princeton University Art Gallery in New Jersey Jan. 27-June 10, 2007.

"Treasures from Olana: Landscapes by Frederic Edwin Church" contains many works that are studies or sketches, small-scale but complete versions of his best-selling large pieces. Included is the study for "The Heart of the Andes," which hung in Olana's east parlor just off the home's entryway.

Church's goal in the painting was to present the natural variety of Ecuador, from the lush jungles to the bare plateaus to the snowcapped peaks.

"He really took landscape around the world and brought his audience there with him," said Paul D'Ambrosio, the museum's chief curator. "You think of Church as somebody who was able to transport his audience to where he was."

The centerpiece of the exhibit is "El Khasne, Petra," produced exclusively for his wife Isabel. She didn't accompany him on a visit to the ancient city in present-day Jordan that was rediscovered by archaeologists in the early 1800s.

The painting shows the facade of a classical temple cut from the cliffs, framed by the opening of a dark cavern. "Imagine this fairy like Temple blazing like sunlight among those savage black rocks," Church wrote to a friend. He gave it a prominent place above a fireplace in Olana's sitting room, opposite a window looking out on the Hudson.

"If you want a personal view of Church, if you want to understand him on the basis of what he chose to keep and live with, this is what you have to see so that you can understand what was important to him," D'Ambrosio said. "And you see virtually his entire career, his entire life in this group of paintings."

Born in 1826 into a wealthy family in Hartford, Conn., an 18-year-old Church became a student of Hudson River School founder Thomas Cole just before his death. Church got his start with pastoral scenes along the river, such as the one in "The Catskill Creek." Green trees reflect on still water near a farmhouse, mountains rising in the distance.

Church soon took on more fantastic subjects, as evidenced by his 1857 classic "Niagara." The study for the painting, with its point of view from the treacherous brink of the falls, is part of the exhibit. Another he painted while "tossing in the surging foam" during a 40-minute boat voyage near the misty base of the falls, lending "Under Niagara" a sense of artistic immediacy.

Church died in 1900, but Olana - his three-dimensional masterpiece - stayed in the family until the state acquired it in the 1960s. The exhibit will be on tour for two years, while parts of the home close for preservation work.
