6 A wall is called isodomum when all the courses are of equal height; pseudisodomum, when the rows of courses do not match but run unequally. Both kinds are strong: first, because the rubble itself is of close texture and solid, unable to suck the moisture out of the mortar, but keeping it in its moist condition for a very long period; secondly, because the beds of the stones, being laid smooth and level to begin with, keep the mortar from falling, and, as they are bonded throughout the entire thickness of the wall, they hold together for a very long period.

Fir: it contains a great deal of air and fire with very little moisture and the earthy, so that, as its natural properties are of the lighter class, it is not heavy. Hence, its consistence being naturally stiff, it does not easily bend under the load, and keeps its straightness when used in the framework. But it contains so much heat that it generates and encourages decay, which spoils it; and it also kindles fire quickly because of the air in its body, which is so open that it takes in fire and so gives out a great flame.
Vitruvius
It is a fearful thing to hate whom God hath loved. To look upon another-his weaknesses, his sins, his faults, his defects is to look upon one who is suffering. He is suffering from negative passions, from the same sinful human corruption from which you yourself suffer. This is very important: do not look upon him with judgmental eyes of comparison, noting the sins you assume you'd never commit. Rather, see him as a fellow sufferer, a fellow human being who is in need of the very healing of which you are in need. Help him, love him, pray for him do unto him as you would have him do unto you.

The theory of perspective was taught in painting schools from the sixteenth century onward according to principles laid down by the masters... However, their treatises on perspective had on the whole been precept, rule, and ad hoc procedure; they lacked a solid mathematical basis. In the period from 1500 to 1600 artists and subsequently mathematicians put the subject on a satisfactory deductive basis, and it passed from quasi-empirical art to a true science. Definitive works on perspective were written much later by eighteenth-century mathematicians Brook Taylor and J. H. Lambert.

It would be wrong to suppose that the man of any particular period always looks upon past times as below the level of his own, simply because they are past. It is enough to recall that to the seeming of Jorge Manrique, "Any time gone by was better."... From A. D. 150 on, this impression of a shrinking of vitality, of a falling from position, of decay and loss of pulse shows itself increasingly in the Roman Empire. Had not Horace already sung: "Our fathers, viler than our grandfathers, begot us who are even viler, and we shall bring forth a progeny more degenerate still?"

When the Soviet government is experiencing a difficult period and plots are being hatched by bourgeois elements and when at a critical moment we manage to lay bare these plots - do they think they are discovered accidentally? Oh, no, not accidentally. They are discovered because the plotters live among the masses, because they cannot succeed in their plots without the workers and peasants and it is there that, in the long run, they run up against people who go to that badly organised, as they said here, Cheka and say that exploiters are gathered in a certain place.
