When we turn to the poetic and literary utterances of the more civilised nations on this subject we cannot but be struck by the range and intensity of the emotions expressed--from the beautiful threnody of David over his friend whose love was passing the love of women, through the vast panorama of the Homeric Iliad, of which the heroic friendship of Achilles and his dear Patroclus forms really the basic theme, down to the works of the great Greek age--the splendid odes of Pindar burning with clear fire of passion, the lofty elegies of Theognis, full of wise precepts to his beloved Kurnus, the sweet pastorals of Theocritus, the passionate lyrics of Sappho, or the more sensual raptures of Anacreon. Some of the dramas of Æschylus and Sophocles--as the “Myrmidones” of the former and the “Lovers of Achilles” of the latter--appear to have had this subject for their motive[17]; and many of the prose-poem dialogues of Plato were certainly inspired by it. Then coming to the literature of the Roman age, whose materialistic spirit could only with difficulty seize the finer inspiration of the homogenic love, and which in such writers as Catullus and Martial could only for the most part give expression to its grosser side, we still find in Vergil, a noble and notable instance. His second Eclogue bears the marks of a genuine passion; and, according to some,[18] he there under the name of Alexis immortalises his own love for the youthful Alexander. Nor is it possible to pass over in this connection the great mass of Persian literature, and the poets Sadi, Hafiz, Jami, and many others, whose names and works are for all time, and whose marvellous love-songs (“Bitter and sweet is the parting kiss on the lips of a friend”) are to a large extent, if not mostly, addressed to those of their own sex.[19]
