Although monogamy was the only one of all known forms of the family in which modern sexlove could develop, this does not imply that it developed exclusively or even principally as mutual love of man and wife. The very nature of strict monogamy under man's rule excluded this. Among all historically active, i. e., ruling, classes matrimony remained what it had been since the days of the pairing family—a conventional matter arranged by the parents. And the first historical form of sexlove as a passion, as an attribute of every human being (at least of the ruling classes), the specific character of the highest form of the sexual impulse, this first form, the love of the knights in the middle ages, was by no means matrimonial love, but quite the contrary. In its classic form, among the Provençals, it heads with full sails for adultery and their poets extol the latter. The flower of Provençal love poetry, the Albas, describe in glowing colors how the knight sleeps with his adored—the wife of another—while the watchman outside calls him at the first faint glow of the morning (alba) and enables him to escape unnoticed. The poems culminate in the parting scene. Likewise the Frenchmen of the north and also the honest Germans adopted this style of poetry and the manner of knightly love corresponding to it. Old Wolfram von Eschenbach has left us three wonderful "day songs" treating this same questionable subject, and I like them better than his three heroic epics.
