(Peter d'), one of the most famous philosophers and physicians of his age, born in the year 1250, in a village about four miles from Padua. He studied some time at Paris, and was there promoted to the degree of doctor in philosophy and physic. When he came to practise as a physician, he is said to have inflicted on very large sums for his visits: we are not told what he demanded for the visits he made in the place of his residence; but it is affirmed, that he would not attend the sick in any other place under 150 florins a day; and when he was sent for by Pope Honorius IV. he demanded 400 ducats for each day's attendance. He was suspected of magic, and prosecuted by the Inquisition on that account. "The common opinion of almost all authors (says Naude) is, that he was the greatest magician of his age; that he had acquired the knowledge of the seven liberal arts, by means of the seven familiar spirits, which he kept inclosed in a crystal; and that he had the dexterity to make the money he had spent come back into his purse." The same author adds, that he died before the process against him was finished, being then in the 80th year of his age; and that, after his death, they ordered him to be burnt in effigy, in the public place of the city of Padua; defaming thereby to strike a fear into others of incurring the like punishment; and to suppress the reading three books which he had wrote; the first being the Heptameron, which is printed at the end of the first volume of Grigippa's work; the second, that which is called by Trithemius, Elucidarium necromanticum Petri de Albano; and the last, that which is intitled by the same author, Liber experimentorum mirabilium de annulis secundum xxviii. mansiones luna. His body being secretly taken up by his friends, escaped the vigilance of the inquisitors, who would have burnt it. It was removed several times, and was at last placed in the church of St Augustin, without an epitaph or any mark of honour. The most remarkable book which Apono wrote, was that which procured him the surname of Conciliator; he wrote also a piece intitled De medicina omnimoda. There is a story told of him, that, having no well in his house, he caused his neighbour's to be carried into the street by devils, when he heard they had forbidden his maid fetching water there. He had much better (says Mr Bayle): have employed the devils to make a well in his own house, and have stopped up his neighbour's; or, at least, transported it into his house, rather than into the street.
