The obscenity of parts of the original does not really detract in the least from the beauty and tenderness of the motive of the story; and we must remember that what we call moral or immoral in style depends very much upon the fashion of an age and time.
Now it is exactly the same kind of moral charm that distinguishes the best of the old English romances--a charm which has nothing to do with the style, but everything to do with the feeling and suggestion of the composition.

But in some of the old romances, the style too has a very great charm of quaintness and simplicity and sincerity not to be imitated to-day.

In this respect the older French romances, from which the English made their renderings, are much the best.

And the best of all is said to be "Amis and Amile," which the English rendered as "Amicus and Amelius." Something of the story ought to interest you.
The whole subject of this romance is the virtue of friendship, though this of course involves a number of other virtues quite as distinguished.

Amis and Amile, that is to say Amicus and Amelius, are two young knights who at the beginning of their career become profoundly attached to each other.
Not content with the duties of this natural affection, they imposed upon themselves all the duties which chivalry also attached to the office of friend.
