The standing figures in the door proper are of women, and represent Truth (on the right) and Research (on the left). Research holds the torch of knowledge or learning, and Truth a mirror and a serpent, the two signifying that in all literature, wisdom (of which the serpent is the emblem) and careful observation (typified by the mirror, with its accurate reflection of external objects) must be joined in order to produce a consistent and truthful impression upon the reader. The smaller panels below contain a design of conventional ornament with cherubs or geniuses supporting a cartouche, on which the mirror or serpent of the larger panels is repeated. =Mr. Macmonnies’s Bronze Door.=--In Mr. Macmonnies’s design the tympanum is occupied by a composition which he has entitled, _Minerva Diffusing the Products of Typographical Art_. The Goddess of Learning and Wisdom--a fit guardian to preside at the main portal of a great library--is seated in the centre upon a low bench. On either side is a winged genius, the messengers of the goddess, each carrying a load of ponderous folios which she is dispatching as her gift to mankind. To the right is her owl, perched solemnly on the bench on which she is sitting. She wears the conventional helmet and breastplate--the latter the Ægis, with its Medusa’s Head--of ancient art, but in her wide, full skirt, with its leaf-figure pattern, the artist has adopted a more modern motive. The Latin title of Mr. Macmonnies’s subject, _Ars Typographica_, and various symbolical ornaments are introduced in the background. To the left and right, enclosed in a laurel wreath, are a Pegasus and a stork. The former stands, of course, for the poetic inspiration which gives value to literature. The stork, commonly symbolizing filial piety, may be taken here, if one chooses, as typifying the faithful care of the inventors of printing and their disciples in multiplying the product of that inspiration. To the left, also, are an hour-glass, an inking-ball, and a printer’s stick; and on the other side of the panel, an ancient printing-press. [Illustration: TRADITION--TYMPANUM OF BRONZE DOOR.--BY OLIN L. WARNER.] Each of the small panels in the upper portion of the doors below is in the shape of a tympanum, and is occupied by a conventionally decorative design composed of a wreath with floating ribbons, enclosing a cartouche on which are inscribed the words “Honor to Gutenberg”--the Inventor of Printing. Each of the upright panels contains the figure of a young and beautiful woman, clad in a robe of the same design as that worn by Minerva, and carrying two tall flaming torches. The figure in the left-hand leaf represents _The Humanities_, the soft contours of her face expressing the gentle and generous liberalities of learning. Her companion stands for _Intellect_, and the lines of her face are of a bolder and severer character. [Illustration: (decorative archway)] MAIN ENTRANCE HALL.
