Plutarch's Natural Questions (10-12)

WHETHER that heat is good against cold? Or that it quenches heat, by diluting the wine and destroying its strength? Or that the aqueous and aerial part of wine (which is therefore prone to mutation) is stayed by the throwing in of terrene parts, whose nature it is to constipate and condense? Moreover, salts with the sea-water, attenuating and colliquating whatever is foreign and superfluous, suffer no fetidness or putrefaction to breed. Besides, the gross and terrene parts, being entangled with the heavy and sinking together, make a sediment or lees, and so make the wine fine.

OF all the senses, smelling causes nauseousness the most, and of all the passions of the mind, fear. For men tremble and shake and bewray themselves upon apprehension of great danger. They that sail in a river are troubled with neither of these. And the smell of sweet and potable water is familiar to all, and the voyage is without danger. On the sea an unusual smell is troublesome; and men are afraid, not knowing what the issue may be. Therefore tranquillity abroad avails not, while an estuating and disturbed mind disorders the body.

Is it for that the winds, slipping the smooth oil, have no force, nor cause any waves? This may be probably said in respect of things external; but they say that divers take oil in their mouths, and when they spout it out they have light at the bottom, and it makes the water transparent; so that the slipping of the winds will not hold good here for an argument. Therefore it is to be considered, whether the sea, which is terrene and uneven, is not compacted and made smooth by the dense oil; and so the sea, being compact in itself, leaves passes, and a pellucidity penetrable by the sight. Or whether that the air, which is naturally mixed with the sea, is lucid, but by being troubled grows unequal and shady; and so by the oil’s density, smoothing its inequality, the sea recovers its evenness and pellucidity.
