James J. Walsh, Old-Time Makers of Medicine
“ Basil Valentine is only one of a number of men who worked faithfully and did much both for medical science and professional life during the thousand years from the fall of Rome to the fall of Constantinople, when, according to what used to be commonly accepted opinion, men were not animated by the spirit of research and of fine incentive to do good to men that we are so likely to think of as belonging exclusively to more modern times. A man whom he greatly influenced, Paracelsus, took up the tradition of scientific investigation where Basil Valentine had left it. ”
