Thus conducting himself, Antony was beloved by all. He subjected himself in sincerity to the good men whom he visited, and learned thoroughly where each surpassed him in zeal and discipline. He observed the graciousness of one; the unceasing prayer of another; he took knowledge of another’s freedom from anger and another’s loving-kindness; he gave heed to one as he watched, to another as he studied; one he admired for his endurance, another for his fasting and sleeping on the ground; the meekness of one and the long-suffering of another he watched with care, while he took note of the piety towards Christ and the mutual love which animated all. Thus filled, he returned to his own place of discipline, and henceforth would strive to unite the qualities of each, and was eager to show in himself the virtues of all. With others of the same age he had no rivalry; save this only, that he should not be second to them in higher things. And this he did so as to hurt the feelings of nobody, but made them rejoice over him. So all they of that village and the good men in whose intimacy he was, when they saw that he was a man of this sort, used to call him God-beloved. And some welcomed him as a son, others as a brother.
Athanasius, Life of Saint Anthony, translated by H. Ellershaw.
In all things by which praise is won, Leon Battista was from his childhood the first. Under the pressure of poverty, he studied both civil and canonical law for many years, till exhaustion brought on a severe illness. In his twenty-fourth year, finding his memory for words weakened, but his sense of facts unimpaired, he set to work at physics and mathematics. And all the while he acquired every sort of accomplishment and dexterity, cross-examining artists, scholars and artisans of all descriptions, down to the cobblers, about the secrets and peculiarities of their craft. Painting and modelling he practiced by the way, and especially excelled in admirable likenesses from memory. Great admiration was excited by his mysterious ‘camera obscura,’ in which he showed at one time the stars and the moon rising over rocky hills, at another wide landscapes with mountains and gulfs receding into dim perspective, and with fleets advancing on the waters in shade or sunshine. And that which others created he welcomed joyfully, and held every human achievement which followed the laws of beauty for something almost divine. To all this must be added his literary works, first of all those on art, which are landmarks and authorities of the first order for the Renaissance of Form, especially in architecture; then his Latin prose writings — novels and other works — of which some have been taken for productions of antiquity; his elegies, eclogues, and humorous dinner-speeches. He also wrote an Italian treatise on domestic life in four books; and even a funeral oration on his dog. His serious and witty sayings were thought worth collecting, and specimens of them, many columns long, are quoted in his biography. And all that he had and knew he imparted, as rich natures always do, without the least reserve, giving away his chief discoveries for nothing.
