Institutio Oratoria

And in Latin ancient writers ended a number of words with d, as may be seen on the column adorned with the beaks of ships, which was set up in the forum in honour of Duilius. [*]( The ablative originally terminated in d; e.g. pugnandod, marid, navaled, pracdad, etc., on the base of the column of Duilius. ) Sometimes again they gave words a final g, as we may still see in the shrine of the Sun, close to the temple of Quirinus, where we find the word uesperug, which we write uesperugo (evening star).

I have already spoken of the interchange of letters [*](I. iv. 12–17.) and need not repeat my remarks here: perhaps their pronunciation corresponded with their spelling.
