The last panel represents Indigo as The Light of Science. The figure represents Astronomy, who is guided by the soul (figured as a butterfly fluttering above her head) to explore the movement of the stars. The cherubs represent various phases of astronomical study. One of the figures, for example, explains the theory of mathematics, showing on the fingers of the hand that one is the unit of everything; a second looks through a telescope; and others are studying books and making calculations.

SENATE READING ROOM.

At the end of the corridor leading to the House Reading Room, is a little lobby, from which one enters the Southwest Pavilion, or Senate Reading Room, reserved for the use of members of the Senate. The little lobby itself is one of the most beautiful examples of pure architectural design to be found in the Library. The walls are of Vermont marble—the same as in the corridor—panelled with Sienna marble. The moulded ceiling is finished entirely in gold, with a central rosette, surrounded by coffers and conventional Greek mouldings, one of which, a rather elaborate fret, is laid upon a ground of deep red. The whole effect of the decoration, taken in connection with the low light which prevails, is remarkably fine—a combination of great richness with soberness and refinement.

The Senate Reading Room is finished in much the same style as the House Reading Room, but with less elaboration of ornament. On the whole, the effect, though quieter, is perhaps more restful and satisfying. A toilet room, leading from the lobby just spoken of, cuts off a portion of the pavilion, but allows space above for a low gallery enclosed by a delicately carved balustrade of Sienna marble. Below, the oak dado is ornamented with delicate inlaid arabesques of white mahogany. Above the dado the walls are covered with figured red silk. In the southwest corner is a fireplace of Sienna marble, with a sculptured panel of the same material by Mr. Herbert Adams. The design shows an eagle with arrows in his claws, and an American shield supported by flying cherubs. The doorhead tympanum is of oak, like those in the House Reading Room, and contains a carved panel, also by Mr. Adams, with a heraldic shield bearing the monogram, “U. S. A.,” and supported by mermaids. The gold ceiling contains six square panels, each containing four graceful female figures holding garlands in their hands—the work of Mr. William A. Mackay.

THE NORTH CORRIDOR.

The corridor leading to the north from the Main Entrance Hall is, as has been said, similar in design to that opening into the Congressional Reading Rooms. The design of the floor and ornament upon the arches is somewhat different, however. The tympanums which it contains are ornamented by a series of paintings, by Mr. Edward Simmons, representing the nine Muses.

Mr. Simmons’s Paintings.—The Muses, according to the Greek mythology, were the goddesses of the various departments of Art, Poetry, and Science. Apollo, the God of Song, was their father, and Mnemosyne (Memory) their mother. Their names, given in the order in which they occur in Mr. Simmons’s series, beginning at the south end of the corridor, were as follows: Melpomene, Clio, Thalia, Enterpe, Terpsichore, Erato, Polyhymnia, Urania, and Calliope. Melpomene was the Muse of Tragedy; Clio, of History; Thalia, of Comedy and Bucolic Poetry; Enterpe, of Lyric Song; Terpsichon, of Dancing; Erato, of Erotic Poetry; Polyhymnia, of Sacred Song; Urania, of Astronomy; and Calliope, of Epic Poetry.

MELPOMENE.—BY EDWARD SIMMONS.

In Mr. Simmons’s panels, each of the Muses is shown as a seated figure. On either side a laurel wreath is displayed, as the general symbol of intellectual pursuits, and the background is diversified by curving lines of smoke proceeding from the flame of a torch or a censer—thus signifying the inspiration of Art and Poetry. In several of the tympanums the Muse is accompanied by little geniuses who serve to bring out the special character of the central figure. In the panel devoted to Thalia the genius is a satyr, with goat’s legs, and carrying a pair of Pan’s pipes. The Muse playfully catches him in a fold of her garment—the whole suggesting the rustic sportiveness of the early Greek Comedy. Certain of the panels, also, contain various distinguishing objects. Melpomene, for example, is accompanied by a tragic mask; Clio by a helmet, for the warlike exploits recorded by History; Thalia, by a comic mask; Urania by a celestial globe. Terpsichore is represented as if swaying to the music of the dance, and is striking a pair of cymbals. Erato is nude, and bears a rose—the flower of love—in her hand. Polyhymnia holds an open book in her lap. One of the geniuses in the tympanum of Calliope holds a scroll, and the other some peacock’s feathers—the latter symbolical, perhaps, of the dignity and beauty of the Epic.
