Herren, Michael W., “Cicero redivivus apud scurras: some early medieval treatments of the great orator”, in: Deusen, Nancy (ed.), Cicero refused to die: Ciceronian influence through the centuries, Presenting the Past 4, Leiden, Boston: Brill, 2013. 1–4.  
What this chapter offers on the life and doings of Cicero is mostly skurril, but one example does verge upon the scurrilous. Early medieval writers and even later ones read many of the authors of Latin antiquity without having an inkling of their lifetime or careers. An example presented in the chapter is not only scurrilous but also shocking. It comes from a collection of Priscian glosses found in a Freising manuscript of the ninth century. The last example involves a more refined treatment of Cicero by an author who may be regarded as exemplifying the older notion of a scurra, namely, "a fashionable city idler." It refers to Virgil the Grammarian, a refined Irish gentleman of the 7th century, whose writings combine the serious treatment of grammar with parody, verbal wit, and much that is perplexing.
