The floors, walls, and vaulted ceiling are of pink Knoxville marble; the floor is inlaid with patterns of brown Knoxville and Levanto marble. The bronze statue to the left as one enters is a representation of Sir Harry Vane, governor of the Massachusetts Bay Colony in 1636 and 1637, by Frederic MacMonnies.
When entering the vestibule, the visitor faces three sets of bronze doors created by Daniel Chester French and commissioned specifically for the Library. Each door weighs 1500 pounds. The allegorical figures, modeled in low relief, represent Music and Poetry (left), Knowledge and Wisdom (center), and Truth and Romance (right).http://www.unitedmarble.com/assets/Blog-Boston-Public-Library-McKim-555x250.jpg
