Logres, usually referring in a vague way to Arthur's kingdom, is often the setting for adventure and romance, as in Chretien de Troyes and the Vulgate cycle. Logres may be derived from either Welsh Lloegr or from Locryn, Brutus' successor and generally defined as the territory south of the Humber and east of the Severn. Welsh texts referred to England as "Lloegyr", Latinized as "Loegria" and later transformed into "Logres".
