Astronomy holds a lens, such as is used in a telescope, in her right hand, and in her left the globe of Saturn surrounded by its rings—selected as being perhaps the best known and most easily distinguished of all the planets. She stands on the sphere of the earth, beyond which, to the left, is the quarter moon. The lines of her drapery with their slow curves are suggestive, in a way, of the orbits of the heavenly bodies. They flow in long lines, enveloping her figure in the strength which proceeds from complete harmony.
Chemistry is shown with her left foot placed upon a piece of chemical apparatus and holding in her right hand a glass retort, in which she is distilling a liquid. The necessary heat, manifested by the ascending vapor which curls about the vessel, is from the mouth of the serpent—the emblem of fecundity and life, breathing the element of life, fire. The serpent is coiled about an hour-glass, which is significant of the exact measurement of time necessary in chemical experiments. The face of the figure is more worn, on account of the anxious nature of her employment, than would comport with the character of an out-of-door science like Botany or Zoölogy. She is draped somewhat in the eastern manner, like a sibyl, thus recalling the occult character ascribed to the science during the Middle Ages—when it was called alchemy—and, for that matter, the marvellousness of its results in the laboratories of to-day. A snake wound as a fillet about her hair still further emphasizes this mystic quality.
At either end of the corridor is a tablet bearing a list of names of men distinguished in the sciences which Mr. Shirlaw has depicted; at the north end: Cuvier, the Zoölogist; Linnæus, the Botanist; Schliemann, the Archæologist; and Copernicus, the Astronomer; at the south end: La Grange, the Mathematician; Lavoisier, the Chemist; Rumford, the Physicist; and Lyell, the Geologist. In the penetrations on either side of these two lists of names are the following appropriate inscriptions:—
The first creature of God was the light of sense; the last was the light of reason.
Bacon.
The Light shineth in darkness, and the darkness comprehendeth not.
John 1, 5.
All are but parts of one stupendous whole,
Whose body Nature is, and God the soul.
Pope.
