” Jeronimus Cardanus, that famous Physician of Milan, a great enquirer of Truth, but too greedy a Receiver of it. He left many excellent discourses, Medical, Natural and Astrological; the most suspicious are those two he wrote by admonition in a dream, that is De Subtilitate and Varietate Rerum. Assuredly this learned man hath taken many things upon trust, and although he examined some hath let slip many others. He is of singular use unto a prudent Reader.”—Sir Thomas Browne, Pseudodoxia Epidemica, Bk. i, Chap. viii, 13.
