With the growth of civilisation and the development of personality there slowly crept into the minds of men a distaste for this irregular sexuality and a desire for a less chaotic state of things. This longing and the wish for legitimate heirs gradually overcame promiscuity and, in Greece, led to the establishment of the monogamous system. It must not be assumed, however, that the Greek ideal of marriage bore any resemblance to our modern conception. True, the wife occupied an honoured position as the guardian of hearth and children and was treated by her husband with affection and respect, but she was not free. Nor was her husband expected to be faithful to her. Marriage in no way restricted his liberty, but left him free to seek intellectual stimulation in the society of the hetaerae, and gratification of the senses in the company of his slaves. Love in our sense was unknown to the ancients, and although there is a modern note in the legends of the faithful Penelope, and the love which united Orpheus and Eurydice, yet, so Lucka tells us, these instances should be regarded rather as poetic divinations of a future stage of feeling than actual facts then within the scope of probability. Even Plato, in whom all wisdom and ante-Christian culture culminated, was still, in this respect, a citizen of the old world, for he, too, knew as yet nothing of the spiritual love of a man for a woman. To him the love of an individual was but a beginning, the road to the love of perfect beauty and the eternal ideas.
