But nowadays men can not love seven night but they must have all their desires: that love may not endure by reason; for where they be soon accorded and hasty heat, soon it cooleth. Right so fareth love nowadays, soon hot soon cold: this is no stability. But the old love was not so; men and women could love together seven years, and no licours lusts were between them, and then was love, truth, and faithfulness: and lo, in like wise was used love in King Arthur's days. Wherefore I liken love nowadays unto summer and winter; for like as the one is hot and the other cold, so fareth love nowadays; therefore all ye that be lovers call unto your remembrance the month of May, like as did Queen Guenever, for whom I make here a little mention, that while she lived she was a true lover, and therefore she had a good end.
Sir Thomas Malory
