Multorum autem odiis nullas opes posse obsistere, si antea fuit ignotum, nuper est cognitum. Nec vero huius tyranni solum, quem armis oppressa pertul… - Cicero

Si igitur meliora sunt ea quae natura quam illa quae arte perfecta sunt, nec ars efficit quicquam sine ratione, ne natura quidem rationis expers est habenda. Qui igitur convenit, signum aut tabulam pictam cum aspexeris, scire adhibitam esse artem, cumque procul cursum navigii videris, non dubitare, quin id ratione atque arte moveatur, aut cum solarium vel descriptum vel ex aqua contemplere, intellegere declarari horas arte, non casu, mundum autem, qui et has ipsas artes et earum artifices et cuncta conplectatur consilii et rationis esse expertem putare. Quod si in Scythiam aut in Brittanniam sphaeram aliquis tulerit hanc, quam nuper familiaris noster effecit Posidonius, cuius singulae conversiones idem efficiunt in sole et in luna et in quinque stellis errantibus, quod efficitur in caelo singulis diebus et noctibus, quis in illa barbaria dubitet, quin ea sphaera sit perfecta ratione.

No one can be a sound judge if he does not give due weight to convincing suspicions.

The things possessing most utility also have the greatest amount of dignity, and indeed frequently of beauty also. In temples and colonnades, the pillars are to support the structure, yet they are as dignified in appearance as they are useful. Yonder pediment of the Capitol and those of the other temples are the product not of beauty but of actual necessity; for it was in calculating how to make the rainwater fall off the two sides of the roof that the dignified design of the gables resulted as a by-product of the needs of the structure — with the consequence that even if one were erecting a citadel in heave, where no rain could fall, it would be thought certain to be entirely lacking in dignity without a pediment.
