He also exhibited at an early age a very decided taste for mathematical studies, especially for astronomy; and attended the lectures, both public and private, of Albert Brudzewski, then mathematical professor at Cracow. Under his tuition, Copernicus, as we shall hereafter call him, became acquainted with the works of the astronomer, John Müller, (now more commonly known by his assumed appellation of Regiomontanus,) and the reputation of this celebrated man is said to have exercised a marked influence in deciding the bent of his future studies. Müller died at Rome a few years after the birth of Copernicus, and when the latter had reached an age capable of appreciating excellence and nourishing emulation, he found Müller’s works disseminated through every civilized country of Europe, his genius and acquirements the subject of universal admiration, and his premature death still regretted as a public calamity. The feelings to which the contemplation of Müller’s success gave rise, were still more excited by a journey into Italy, which Copernicus undertook about the year 1495. One of his brothers and his maternal uncle were already settled in Rome, which was therefore the point to which his steps eventually tended. He quitted home in his twenty-third year; when his diligence in cultivating the practical part of astronomy had already procured for him some reputation as a skilful observer. It seems to have been in contemplation of this journey that he began to study painting, in which he afterwards became a tolerable proficient. Bologna was the first place at which he made any stay, being drawn thither by the reputation of the astronomical professor, Dominic Maria Novarra. Copernicus was not more delighted with this able instructor than Novarra with his intelligent pupil. He soon became an assistant and companion of Novarra in his observations, and in this capacity acquired considerable distinction, so that on his departure from Bologna and arrival at Rome, he found that his reputation had preceded him. He was appointed to a professorship in that city, where he continued to teach mathematics for some years with considerable success.
