Heilbrunn Timeline of Art HistoryThe Heilbrunn Timeline of Art History from the Metropolitan Museum of Art is a chronological, geographical, and thematic exploration of the history of art from around the world, as illustrated by the Museum's collection. It is an invaluable reference and research tool for students, educators, scholars, and anyone interested in the study of art history and related subjects. First launched in 2000, the Timeline extends from prehistory to the present day. The Museum's curators, conservators, and educators research and write the Timeline; it continues to expand in scope and depth and reflect the most up-to-date scholarship.
