The works attributed to this very differently, though never unfavourably, estimated tale-teller--at least those which concern us--are _Percevale le Gallois_, _Le Chevalier a[22] la Charette_, _Le Chevalier au Lyon_, _Erec et Enide_, _Cliges_, and a much shorter _Guillaume d'Angleterre_. This last has nothing to do with the Conqueror (though the title has naturally deceived some), and is a semi-mystical romance of the group derived from the above-mentioned legend of St. Eustace, and represented in English by the beautiful story of _Sir Isumbras_. It is very doubtfully Chrestien's, and in any case very unlike his other work; but those who think him the Arthurian magician might make something of it, as being nearer the tone of the older Graal stories than the rest of his compositions, even _Percevale_ itself. Of these, all, except the _Charette_, deal with what may be called outliers of the Arthurian story. _Percevale_ is the longest, but its immense length required, by common confession, several continuators;[23] the others have a rather uniform allowance of some six or seven thousand lines. _Cliges_ is one of the most "outside" of all, for the hero, though knighted by Arthur, is the disinherited heir of Constantinople, and the story is that of the recovery of his kingdom. _Erec_, as the second part of the title will truly suggest, though the first may disguise it, gives us the story of the first of Tennyson's original _Idylls_. The _Chevalier au Lyon_ is a delightful romance of the Gawain group, better represented by its English adaptation, _Ywain_, than any other French example. _Percevale_ and the _Charette_ touch closest on the central Arthurian story, and the latter has been the chief battlefield as to Chrestien's connection therewith, some even begging the question to the extent of adopting for it the title _Lancelot_.
