Thus having evinced, at least made dubious, the Sun is not the Author of this Blackness, how, and when this tincture first began is yet a Riddle, and positively to determine, it surpasseth my presumption. Seeing therefore we cannot discover what did effect it, it may afford some piece of satisfaction to know what might procure it. It may be therefore considered, whether the inward use of certain waters or fountains of peculiar operations, might not at first produce the effect in question. For, of the like we have records in _Aristotle, Strabo_ and _Pliny_, who hath made a collection hereof, as of two fountains in _Bœotia_, the one making Sheep white, the other black; of the water of _Siberis_ which made Oxen black, and the like effect it had also upon men, dying not only the skin, but making their hairs black and curled. This was the conceit of _Aristobulus_, who received so little satisfaction from the other, or that it might be caused by heat, or any kind of fire, that he conceived it as reasonable to impute the effect unto water. Secondly, It may be perpended whether it might not fall out the same way that _Jacobs_ cattle became speckled, spotted and ring-straked, that is, by the Power and Efficacy of Imagination; which produceth effects in the conception correspondent unto the phancy of the Agents in generation; and sometimes assimilates the Idea of the Generator into a reality in the thing ingendred. For, hereof there pass for current many indisputed examples; so in _Hippocrates_ we read of one, that from an intent view of a Picture conceived a _Negro_; And in the History of _Heliodore_ of a Moorish Queen, who upon aspection of the Picture of _Andromeda_, conceived and brought forth a fair one. [SN: Vide plura apud _Tho. Fienum_, de viribus imaginationis.] And thus perhaps might some say was the beginning of this complexion: induced first by Imagination, which having once impregnated the seed, found afterward concurrent co-operation, which were continued by Climes, whose constitution advantaged the first impression. [SN: _Why Beares_ etc. _white in some places._] Thus _Plotinus_ conceiveth white Peacocks first came in. Thus many opinion that from aspection of the Snow, which lieth long in Northern Regions, and high mountains. Hawks, Kites, Beares, and other creatures become white; and by this way _Austin_ conceiveth the devil provided, they never wanted a white spotted Ox in _Egypt_; for such an one they worshipped, and called _Apis_.
