11. We cannot without partiality omit all caution even of holy Writers, and such whose names are venerable unto all posterity: not to meddle at all with miraculous Authors, or any Legendary relators, we are not without circumspection to receive some Books even of authentick and renowned Fathers. So are we to read the leaves of _Basil_ and _Ambrose_, in their Books entituled _Hexameron_, or _The Description of the Creation_; Wherein delivering particular accounts of all the Creatures, they have left us relations sutable to those of _Ælian_, _Plinie_, and other Natural Writers; whose authorities herein they followed, and from whom most probably they desumed their Narrations. And the like hath been committed by _Epiphanius_, in his Physiologie: that is, a Book he hath left concerning the Nature of Animals. With no less caution must we look on _Isidor_ Bishop of _Sevil_; who having left in twenty Books, an accurate work _De Originibus_, hath to the Etymologie of Words, super-added their received Natures; wherein most generally he consents with common Opinions and Authors which have delivered them. 12. _Albertus_ Bishop of _Ratisbone_, for his great Learning and latitude of Knowledge, sirnamed _Magnus_. Besides Divinity, he hath written many Tracts in Philosophy; what we are chiefly to receive with caution, are his Natural Tractates, more especially those of Minerals, Vegetables, and Animals, which are indeed chiefly Collections out of _Aristotle_, _Ælian_, and _Pliny_, and respectively contain many of our popular Errors. A man who hath much advanced these Opinions by the authority of his Name, and delivered most Conceits, with strict Enquiry into few. In the same _Classis_ may well be placed _Vincentius Belluacensis_, or rather he from whom he collected his _Speculum naturale_, that is, _Guilielmus de Conchis_; and also _Hortus Sanitatis_, and _Bartholomeus Glanvil_, sirnamed _Anglicus_, who writ _De proprietatibus Rerum_. Hither also may be referred _Kiranides_, which is a Collection out of _Harpocration_ the Greek, and sundry Arabick Writers; delivering not onely the Natural but Magical propriety of things; a Work as full of Vanity as Variety; containing many relations, whose Invention is as difficult as their Beliefs, and their Experiments sometime as hard as either. 13. We had almost forgot _Jeronimus Cardanus_ that famous Physician of _Milan_, a great Enquirer of Truth, but too greedy a Receiver of it. He hath 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 & Varietate Rerum_. Assuredly this learned man hath taken many things upon trust, and although examined some, hath let slip many others. He is of singular use unto a prudent Reader; but unto him that onely desireth Hoties, or to replenish his head with varieties; like many others before related, either in the Original or confirmation, he may become no small occasion of Error.
