| 1. | Justice consists in consonance with it, Derivable by no created good, Whose very cause depends upon its beam.. - from The Divine Comedy, Complete by Dante Alighieri |
| 2. | The teachers of harmony compare the sounds and consonances which are heard only, and their labour, like that of the astronomers, is in vain. - from The Republic by Plato |
| 3. | For they investigate only the numbers of the consonances which are heard, and ascend no higher,--of the true numerical harmony which is unheard, and is only to be found in problems, they have not even a conception. - from The Republic by Plato |
