The emblem of a lion holding a book denotes the Evangelist Mark "because he opens his gospel by describing St. John the Baptist as 'the voice of one crying in the wilderness' (Mark 1:3), because he makes the royal dignity of Christ so apparent, and because the lion signifies royalty in allusion to the kingly office of Christ." (Daniel J. Fleming, Education through Stone and Glass; A Study of Decorative Symbolism in Union Theological Seminary, 41) The emblem can be seen on both the Broadway and Quadrangle sides of the Library's facade.
