When I had said these things Aristo, as his habit was, cried out: A return has been decreed in banquets to a very popular and just standard, which, because it was driven away by unseasonable temperance as if by the act of a tyrant, has long remained in exile. For just as those trained in the canons of the lyre declare the sesquialter proportion produces the symphony diapente, the double proportion the diapason, the sesquiterte the diatessaron, the slowest of all, so the specialists in Bacchic harmonies have detected three accords between wine and water - Diapente, Diatrion, Diatessaron. For so they speak and sing, "drink five or three, but not four." For five have the sesquialter proportion, three cups of water being mixed in two of wine; three, the double proportion, two being mixed with one; four, the sesquiterce, three cups of water to one of wine, which is the epitrite proportion for those exercising their minds in the council-chamber or frowning over dialectics, when changes of speeches are expected - a sober and mild mixture. But in regard to those proportions of two to one, that mixture gives the strength by which we are confused and made half drunk, "Exciting the chords of the soul never moved before." For it does not admit of sobriety, nor does it induce the senselessness of pure wine. The most harmonious is the proportion of two to three, provoking sleep, generating the forgetfulness of cares, and like that cornfield of Hesiod," which mildly pacifieth children and heals injuries." It composes in us the harsh and irregular motions of the soul and secures deep peace for it. Against these sayings of Aristo no one had anything to offer in reply, since it was quite evident he was jesting. I suggested to him to take a cup and treat it as a lyre, tuning it to the harmony and order he praised. At the same time a slave came offering him pure wine. But he refused it, saying with a laugh that he was discussing logical not organic music. To what had been said before my father added that Jove seemed to have taken, according to the ancients, two nurses, Ite and Adrastea; Juno one, Euboea; Apollo also two, Truth and Corythalea; but Bacchus several, because he needed several measures of water to make him manageable, trained, milder, and more prudent.
