Commoratio is a forme of speech, by which the Orator knowing whereon the whole waight of his cause doth depend, maketh often recourse thither, and repeateth it many times by variation, whereof there be two kindes, to one which expresseth one thing with may words of the same signification which is called Sinonimia, spoken of before as in this example of Cicero: And shall so great a vertue be expelled, thrust out, banished and cast away from the citie?
Another: What diddest thou covet? What didest thou wish? what diddest thou desire? The other wich declareth one thing with diverse members, divers causes, diverse effectes and deverse reasons, Cicero when Erutius could shew no cause in his accusation, why Roscius should slay his father, he doth first amplifie the wicked fact of Parricide, declaring how great it is, & argueth that without many and great causes, such a wickednesse cannot bee committed, and contendeth that it cannot fall but upon a mischievous and most lewd men: after this he demaundeth of Erutius the cause why Roscius should slay his father, which place because it was strongest in Roscius defence, he tarieth long in it, and very often maketh his returne thither, he often demaundeth the causes of so great and horrible wickednesse, of so shameful a deed, he often amplifieth the greatnesse of the fact, and that which is great indeede, he maketh by his eloquence and vehemencie of his speech wonderfull great.
The use of this figure.
The most usuall practice of this figure is to accuse or defend, and that after a strong and forcible manner.
Where verture useth this figure, it neither acceseth falsly nor defendeth fraudulently, but where craft and ill conscience beare the sway it doth both.
