Simply pausing to recognize the presence of the Northern Cross, we turn to the eastern side of the meridian, where we find Pegasus, with his Great Square. This is one of the most conspicuous figures in the sky. The star at the northeastern corner of the square is Alpheratz, of which I have spoken in the Introduction, as belonging in common to Andromeda and Pegasus. When we come to Cassiopeia I shall point out a remarkable fact relating to Alpheratz and its twin, Gamma Pegasi, about 15 degrees directly south. Every lover of the “classics” of course feels a thrill of pleasure in seeing Pegasus in the sky, “in wild flight and free.” One can spare many of the heroes for the sake of giving him room. Shakespeare’s references to the constellations are much less frequent and definite than one could wish, but he has clearly mentioned one or two, and it may be that he had the starry eidolon of the Winged Horse in his eye when he wrote, in _Troilus and Cressida_: “But let the ruffian Boreas once enrage The gentle Thetis, and anon behold The strong-ribbed bark through liquid mountains cut, Bounding between the two moist elements Like Perseus’ horse.” The constellation extends far westward from the Square, and in the imaginative sky pictures that illustrate old charts of the heavens the star Epsilon (ε) is in the nose of Pegasus, as he stretches out his neck to reach his foal, Equuleus. But the horse, with his feet toward the north, is shown upside down, unless you turn your back to the south when looking at him. The star Beta (β) is attractive on account of its neighbors forming a striking triangle with it; but the space within the Square is relatively vacant. Alpha (α) and Beta (β) are respectively Markab, the “Saddle,” and Scheat (signification uncertain).
