Of Cledonius personally we know nothing; but it is not improbable that he may have been attached to the Auditorium or University established in the capitolium of Constantinople, an institution to which we find an allusion in p. 1866. (Comp. Godofr. ad Cod. Theodos.
14. tit. 9 vol. v. p. 203, &c.)
the author of an essay upon Latin grammar, published by Putschius from a single corrupt and imperfect MS., inscribed Ars Cledonii Romani Senatoris, Constantinopolitani Grammatici.
It is professedly a commentary on the celebrated treatise of Donatus, and to suit the arrangement of that work is divided into two parts, the former, or ars prima,
containing illustrations of the Editio Prima
; the latter, or ars secunda,
of the Editio Secunda.
The only edition is that contained in the Grammaticae Latinae Auctores Antiqui of Putschius, 4to., Hanov. 1605, pp. 1859-1939.
