SUBSECT. I.—Diet rectified in substance.
Diet, [Greek: Diaitaetikae], victus, or living, according to  Fuchsius and others, comprehends those six non-natural things, which I have before specified, are especial causes, and being rectified, a sole or chief part of the cure. Johannes Arculanus, cap. 16. in 9. Rhasis, accounts the rectifying of these six a sufficient cure. Guianerius, tract. 15, cap. 9. calls them, propriam et primam curam, the principal cure: so doth Montanus, Crato, Mercurialis, Altomarus, &c., first to be tried, Lemnius, instit. cap. 22, names them the hinges of our health, no hope of recovery without them. Reinerus Solenander, in his seventh consultation for a Spanish young gentlewoman, that was so melancholy she abhorred all company, and would not sit at table with her familiar friends, prescribes this physic above the rest, no good to be done without it. Aretus, lib. 1. cap. 7. an old physician, is of opinion, that this is enough of itself, if the party be not too far gone in sickness. Crato, in a consultation of his for a noble patient, tells him plainly, that if his highness will keep but a good diet, he will warrant him his former health. Montanus, consil. 27. for a nobleman of France, admonisheth his lordship to be most circumspect in his diet, or else all his other physic will be to small purpose. The same injunction I find verbatim in J. Caesar Claudinus, Respon. 34. Scoltzii, consil. 183. Trallianus, cap. 16. lib. 1. Laelius a Fonte Aeugubinus often brags, that he hath done more cures in this kind by rectification of diet, than all other physic besides. So that in a word I may say to most melancholy men, as the fox said to the weasel, that could not get out of the garner, Macra cavum repetes, quem macra subisti, the six non-natural things caused it, and they must cure it. Which howsoever I treat of, as proper to the meridian of melancholy, yet nevertheless, that which is here said with him in Tully, though writ especially for the good of his friends at Tarentum and Sicily, yet it will generally serve most other diseases, and help them likewise, if it be observed.
