The study of astrology and occult philosophy, to which many of the finest minds of the Middle Ages devoted themselves without molestation from the Church, was never practised with impunity after the Reformation. The Puritans and Presbyterians, taking the Bible for their rule, "suffered not a witch to live;" and, not content with burning the books of those who "used curious arts" after the manner of the Ephesians, they sacrificed the students themselves on the same pile. Hence we hear little of learned and scientific wizards in New England. One remarkable character of this kind seems, however, to have escaped the vigilance of our modern Doctors of the Mosaic Law. Dr. Robert Child came to this country about the year 1644, and took up his residence in the Massachusetts colony. He was a man of wealth, and owned plantations at Nashaway, now Lancaster, and at Saco, in Maine. He was skilful in mineralogy and metallurgy, and seems to have spent a good deal of money in searching for mines. He is well known as the author of the first decided movement for liberty of conscience in Massachusetts, his name standing at the head of the famous petition of 1646 for a modification of the laws in respect to religious worship, and complaining in strong terms of the disfranchisement of persons not members of the Church. A tremendous excitement was produced by this remonstrance; clergy and magistrates joined in denouncing it; Dr. Child and his associates were arrested, tried for contempt of government, and heavily fined. The Court, in passing sentence, assured the Doctor that his crime was only equalled by that of Korah and his troop, who rebelled against Moses and Aaron. He resolved to appeal to the Parliament of England, and made arrangements for his departure, but was arrested, and ordered to be kept a prisoner in his own house until the vessel in which he was to sail had left Boston. He was afterwards imprisoned for a considerable length of time, and on his release found means to return to England. The Doctor's trunks were searched by the Puritan authorities while he was in prison; but it does not appear that they detected the occult studies to which lie was addicted, to which lucky circumstance it is doubtless owing that the first champion of religious liberty in the New World was not hung for a wizard. Dr. Child was a graduate of the renowned University of Padua, and had travelled extensively in the Old World. Probably, like Michael Scott, be had: "Learned the art of glammarye In Padua, beyond the sea;"
