Everett began his public speaking career while he taught at Harvard, which combined with his editorship of the "Review" to bring him some national prominence. He preached at a service held in the United States Capitol that brought him wide notice and acclaim in political circles. In 1822, he delivered a series of lectures in Boston on art and antiquities. The series was well attended, and he repeated it in subsequent years. He made a major speech in December 1823 advocating for American support of the Greeks in their struggle for independence from the Ottoman Empire. This subject was adopted by Daniel Webster, who also made it the subject of a speech in Congress. (Everett's support for Greek independence made him something of a hero in Greece, and his portrait hangs in the National Gallery in Athens.) This collaboration between Webster and Everett was the start of a lifelong political association between the two men.
