The acts of Geoffrey Greygown in the _Gesta Consulum_ are a mass of fable. The fight with the Dane Æthelwulf and that with the Saxon Æthelred are mythical on the face of them, and the writer’s habitual defiance of chronology is carried to its highest point in this chapter. From him we turn to the story of Fulk Rechin. “Ille igitur Gosfridus Grisa Gonella, pater avi mei Fulconis, cujus probitates enumerare non possumus, excussit Laudunum de manu Pictavensis comitis, et in prœlio superavit eum super Rupes, et persecutus est eum usque ad Mirebellum. Et fugavit Britones, qui venerant Andegavim cum prædatorio exercitu, quorum duces erant filii Isoani (Conani). Et postea fuit cum duce Hugone in obsidione apud Marsonum, ubi arripuit eum infirmitas quâ exspiravit; et corpus illius allatum est Turonum et sepultum in ecclesiâ B. Martini” (Fulk Rechin, Marchegay, _Comtes_, p. 376). Whoever was the author of this account, he clearly knew or cared nothing about the stories of the monkish writers, but had a perfectly distinct source of information unknown to them. For their legends he substitutes two things: a war with the count of Poitou, and a war with the duke of Britanny. On each of these wars we get some information from one other authority; the question is how to make this other authority tally with Fulk. 1. As to the Breton war, which seems to be the earlier in date. No one but Fulk mentions the raid of Conan’s sons upon Angers; and M. Mabille (Introd. _Comtes_, p. xlviii) objects to it on the ground that Conan’s sons were not contemporaries of Geoffrey. Conan of Rennes was killed in 992 in a battle with Geoffrey’s son. He had been married in 970 to Geoffrey’s daughter Hermengard (see above, pp. 121, 135). Now a daughter of Geoffrey in 970 must have been almost a child, but it by no means follows that her husband was equally young. On the contrary, he seems to have been sufficiently grown up to take a part in politics twenty years before (Morice, _Hist. Bret._ vol. i. p. 62). It is certain that he had several sons; it is certain that two at least of them were not Hermengard’s; it is likely that none of them were, except his successor Geoffrey. Supposing Conan was somewhat over fifty when killed (and he may have been older still) that would make him about thirty when he married Hermengard; he might have had sons ten years before that, and those sons might very easily head an attack upon their stepmother’s father in 980 or thereabouts. Surely M. Mabille here makes a needless stumbling-block of the chronology.
