“With regard to lime we must be careful that it is burned from a stone which”

— Vitruvius, book De architectura

Source: De architectura (The Ten Books On Architecture) (~ 15BC), Book II, Chapter V "Lime" Sec. 1
Context: With regard to lime we must be careful that it is burned from a stone which, whether soft or hard, is in any case white. Lime made of close-grained stone of the harder sort will be good in structural parts; lime of porous stone, in stucco. After slaking it, mix your mortar, if using pitsand, in the proportions of three parts of sand to one of lime; if using river or sea-sand, mix two parts of sand with one of lime. These will be the right proportions for the composition of the mixture. Further, in using river or sea-sand, the addition of a third part composed of burnt brick, pounded up and sifted, will make your mortar of a better composition to use.

“The reason why lime makes a solid structure on being combined with water and sand seems to be this: that rocks, like all other bodies, are composed of the four elements. Those which contain a larger proportion of air, are soft; of water, are tough from the moisture; of earth, hard; and of fire, more brittle. Therefore, if limestone, without being burned, is merely pounded up small and then mixed with sand and so put into the work, the mass does not solidify nor can it hold together. But if the stone is first thrown into the kiln, it loses its former property of solidity by exposure to the great heat of the fire, and so with its strength burnt out and exhausted it is left with its pores open and empty. Hence, the moisture and air in the body of the stone being burned out and set free, and only a residuum of heat being left lying in it, if the stone is then immersed in water, the moisture, before the water can feel the influence of the fire, makes its way into the open pores; then the stone begins to get hot, and finally, after it cools off, the heat is rejected from the body of the lime.”

“What is called "sponge stone" or "Pompeian pumice" appears to have been reduced by burning from another kind of stone to the condition of the kind which we see. The kind of sponge-stone taken from this region is not produced everywhere else, but only about Aetna and among the hills of Mysia which the Greeks call the "Burnt District," and in other places of the same peculiar nature. …it seems to be certain that moisture has been extracted from the tufa and earth, by the force of fire, just as it is from limestone in kilns.”

“In the groundes bordering uppon tile woods of Arden, which are verie colde, they use lime instead of dung, and thereby they make ye earth most fruitful which was barren before, Now if lime (which is nothing else but a baked or burnt stone within those fierie furnaces, and whose moisture is altogether exhaled, so as there remaineth therin nothing else, but the terrestriall parts replenished with a fierie vertue) be found so rich a soile, I know not why the heat of marle may not nmch better be endured”

“The quantitative investigations of Black on the burning of lime and magnesia alba, in which the balance (previously characterized by the French chemist Jean Rey as "an instrument for clowns") was applied at every turn, led to the rejection of a hypothetical "principle of causticity," and replaced it by a "sensible ingredient of a sensible body," fixed air.”

“We must not burn down the house to kill the rats.”

Context: The whole notion of loyalty inquisitions is a national characteristic of the police state, not of democracy. The history of Soviet Russia is a modern example of this ancient practice. I must, in good conscience, protest against any unnecessary suppression of our rights as free men. We must not burn down the house to kill the rats.
