High atop a hill, about two hours north of Manhattan, stands one of the most celebrated landmarks of the Hudson Valley region: Olana, the opulent Orientalist palazzo of Hudson River School landscape painter Frederic Edwin Church (1826-1900). Church chose the spot for his home because of its commanding views of the beautiful river and its Catskill Mountain surroundings, views that he painted in all seasons. Moreover, a much smaller house directly across the majestic waterway was especially close to his heart: Cedar Grove, the home of Church's teacher Thomas Cole (1801-48). Cole is acknowledged as the founder of the Hudson River School, his Romantic compositions inaugurating the first body of distinctively American landscape paintings.

Now Cedar Grove, the Thomas Cole National Historic Site, is showing "Master, Mentor, Master: Thomas Cole & Frederic Church," an exhibition central to the story of Church's artistic development.
