In Institutio oratoria 1,7,23 and 9,4,39 Quintilian quotes a somewhat idiosyncratic Catonian spelling for dicam and faciam. The manuscripts offer for the first passage both dicae / faciae and dice / facie as variants, whereas the second passage is corrupt, but in all probability has to be emended according to 1,7,23. Recently James Bradford Churchill and Wolfram Ax have advocated the spellings with -e. In contrast, this paper first argues on the basis of a thorough analysis of the two passages (...) for the readings dicae and faciae, which Quintilian believed Cato the elder to have written; secondly it is likely that Cato indeed had used these forms to render the weakened pronunciation of m, which sounded (as we may presume) like a weak e (something like a schwa) to him. Obviously, the exact pronunciation must remain uncertain. (shrink)
