Context paragraphs:
Crucifixion Diptych (van der Weyden): Crucifixion Diptych — also known as Philadelphia Diptych, Calvary Diptych, Christ on the Cross with the Virgin and St. John, or The Crucifixion with the Virgin and Saint John the Evangelist Mourning — is a diptych attributed by some art historians to the Early Netherlandish artist Rogier van der Weyden, completed c. 1460, today in the Philadelphia Museum of Art.  The panels are noted for their technical skill, visceral impact and for possessing a physicality and directness unusual for Netherlandish art of the time.  The Philadelphia Museum of Art describes work as the "greatest Old Master painting in the Museum."

Rocky Steps: The 72 stone steps before the entrance of the Philadelphia Museum of Art, in Philadelphia, Pennsylvania, have become known as the "Rocky Steps" as a result of their appearance in the triple-Oscar-winning film "Rocky" and all of the series' sequels except for "Rocky IV", in which the eponymous character runs up the steps to the song "Gonna Fly Now".  Tourists often mimic Rocky's famous climb, a metaphor for an underdog or an everyman rising to a challenge.  A bronze "Rocky" statue was briefly situated at the top of the steps for the filming of "Rocky III".  This statue, now located at the bottom right of the steps, is a popular photo opportunity for visitors.  The top of the steps offers a commanding view of Eakins Oval, the Benjamin Franklin Parkway, and Philadelphia City Hall.
