Institutio Oratoria

Substitution is however sometimes admitted even in prose, as for instance when Cicero speaks of the army of Canopus which is locally styled Canobus, while the number of authors who have been guilty of transposition in writing Trasumennus for Tarsumennus has succeeded in standardising the error. Similar instances may be quoted. If adsentior be regarded as the correct form, we must remember that Sisenna said adsentio, and that many have followed him on the ground of analogy: on the other hand, if adsentio is the correct form, we must remember that adsentior has the support of current usage.

And yet our fat fool, the fashionable schoolmaster, will regard one of these forms as an example of omission or the other as an instance of addition. Again there are words which when used separately are undoubtedly incorrect, but when used in conjunction excite no unfavourable comment.

For instance dua and tre are barbarisms and differ in gender, but the words duapondo and trepondo [*](Two and three pounds in weight.) have persisted in common parlance down to our own day, and Messala shows that the practice is correct.

It may perhaps seem absurd to say that a barbarism, which is an error in a single word, may be made, like a solecism, by errors in connexion with number or gender. But take on the one hand scala (stairs) and scopa (which literally means a twig, but is used in the sense of broom) and on the other hand hordea (barley) and mulsa (mead): here we have substitution, omission and addition of letters, but the blemish consists in the former case merely in the use of singular for plural,

I merely mention these as instances: I do not wish anyone to think that I have added a fresh problem to a subject into which the obstinacy of pedants has already introduced confusion. The faults which arise in the course of actual speaking require greater penetration on the part of the critic, since it is impossible to cite examples from writing, except in cases where they occur in poetry, as when the diphthong is divided into two syllables in Europai and Asiai [*](The archaic genitive as used by epic poets.) ; or when the opposite fault occurs, called synaeresis or synaloephe by the Greeks and complexio by ourselves: as an example I may quote the line of Publius Varro:

1. turn te flagranti deiectum fulmine Plaethon. [*]( Ph oe thon for Phaëthon. )

If this were prose, it would be possible to give the letters their true syllabic value. I may mention as further anomalies peculiar to poetry the lengthening of a short syllable as in Italiam fato profugus, [*](Aen. i. 6. ) or the shortening of a long such as unĭius ob noxam et furias; [*](Aen. i. 45. ) but in poetry we cannot label these as actual faults.

Errors in sound on the other hand can be detected by the ear alone; although in Latin, as regards the addition or omission of the aspirate, the question may be raised whether this is an error when it occurs in writing; for there is some doubt whether h is a letter or merely a breathing, practice having frequently varied in different ages.
