=Mr. Cox’s Paintings.=--Mr. Cox’s tympanums are thirty-four feet long and nine and a half feet high. At the south end of the room the subject of the decoration is _The Sciences_, and at the north end, _The Arts_. The panels are similar in composition, occupying as they do exactly corresponding positions. On each the design is drawn together by a low marble balustrade, at the centre of which is a semicircular recess enclosing a kind of throne or high marble seat. At either end of the recess, so as to come directly over a pilaster occurring between the doors, is a post bearing a tripod on which incense is burning. The effect is to carry the lines of the architecture below up into the painting. [Illustration: THE ARTS.--BY KENYON COX.] In the panel of _The Arts_, the central throne is occupied by the figure of Poetry, represented as a young and beautiful woman crowned with laurel and bearing an antique lyre. She is seated in an attitude of immediate inspiration, the fold of her garment blowing in the wind, her left hand raised from the chord which she has just struck upon the lyre, and her lips parted in a burst of song. On the steps of her throne are two little geniuses, one writing down her words on a tablet, and the other raising his arms in sympathy as he joins in the rhythmical swing of her song. The first may be taken as personifying the more strictly literary and reflective side of poetry, and the other as standing for its feeling for harmony and music, or, in general, the lyrical element in poetry. In the left-hand portion of the decoration are Architecture and Music, and to the right, Sculpture and Painting--all typified by female figures bearing some appropriate object identifying the art which they represent. Architecture is conceived as the sternest and most dignified of the arts, as shown by her expression of proud abstraction and the severe lines of her drapery. She holds a miniature marble column, and her head is crowned with a circlet of battlements. Music is playing upon a violin, and looking the while upon the pages of a great music-book which a kneeling genius holds open before her. Beside her is a violoncello. Sculpture holds a statuette of a nude female figure, and talks with Painting, who has a palette and brushes. The latter, as representing the gentler and more luxurious art, is shown partly nude, and leaning her head affectionately upon the shoulder of her companion. In the corner of the picture are a vase and two large plates in different styles of decorated pottery--standing for the minor decorative arts. [Illustration: SPRING.--BY BELA L. PRATT.]
