Insular Latinity – its origins, characteristics, affiliations and dissemination – has attracted much attention in the last decade. One area which has benefited from this increased interest is the investigation of the Latin grammars written by Insular scholars: consider, for example, the editions of Insular grammatical writings recently published in the Corpus Christianorum Series Latina. But it is noteworthy that the Anglo-Latin grammarians have profited far less from this upsurge in interest than their Irish counterparts. Although Anglo-Latin as well as Hiberno-Latin texts have been among those recently edited, and have been the subject of several specialized studies, they have failed to excite scholarly attention to the same extent as the Irish works. Their origin, history, relationship and cultural context have not yet been satisfactorily established. Studies such as the series of articles by Louis Holtz, tracing the evolution of the study of grammar in Ireland and the relationship of the surviving texts to one another, are lacking for the Anglo-Latin grammarians. Yet the unknown factors in early England are scarcely fewer. To take one example, the fundamental problem of the rôle of the Irish in the creation of an Anglo-Latin grammatical tradition has hardly been touched upon. Indeed, that the Anglo-Saxons can even be credited with a grammatical tradition of their own has been questioned. Too often, the few surviving Anglo-Latin grammars are held up as an isolated phenomenon and contrasted with the prolific outpourings of a diligent host of Irish anonymi. It is the purpose of this article to investigate the evidence for the study of Latin grammar in England south of the Humber up to the time of its best-known manifestations, the grammars of Tatwine and Boniface, in the early eighth century.
