Thus you see, that the cause of the Ethiopians blacknesse is the curse and naturall infection of blood, and not the distemperature of the Climate; Which also may bee prooued by this example, that these blacke men are found in all parts of Africa, as well without the Tropickes, as within, euen vnto Capo de buona Speranza Southward, where, by reason of the Sphere, should be the same temperature that is in Sicilia, Morea and Candie, where al be of very good complexions.  Wherefore I conclude, that the blacknesse proceedeth not of the hotenesse of the Clime, but as I saide, of the infection of blood, and therefore this their argument gathered of the Africans blacknesse is not able to destroy the temperature of the middle Zone.  Wee may therefore very well bee assertained, that vnder the Equinoctiall is the most pleasant and delectable place of the worlde to dwell in; where although the Sunne for two houres in a yeere be direct ouer their heades, and therefore the heate at that time somewhat of force, yet [Sidenote:  Greatest temperature vnder the Equinoctial] because it commeth so seldome, and continueth so small a time, when it commeth, it is not to bee wayed, but rather the moderate heate of other times in all the yeere to be remembred.  And if the heate at any time should in the short day waxe somewhat vrgent, the coldnesse of the long night there would easily refresh it, according as Henterus sayeth, speaking of the temperature vnder the Equinoctiall.

    Quodque die solis violento incanduit aestu,
    Humida nox reficit, paribusque refrigerat horis.

If the heate of the Sunne in the day time doe burne or parch any thing, the moysture of the night doeth coole and refresh the same againe, the Sunne being as long absent in the night, as it was present in the day.

Also our Aucthour of the Sphere, Johannes de Sacro Bosco, in the Chapter of the Zodiacke, deriueth the Etymologie of Zodiacus, of the Greeke word Zoe, which in Latine signifieth Vita, life; for out of Aristotle hee alleadgeth, that Secundum accessum et recessum solis in Zodiaco, fiunt generationes et corruptiones in rebus inferioribus:  according to the Sunnes going to and fro in the Zodiake, the inferiour bodies take their causes of generation and corruption. [Sidenote:  Vnder the Equinoctiall is greatest generation.] Then it followeth, that where there is most going to and fro, there is most generation and corruption:  which must needes be betweene the two Tropikes; for there the Sunne goeth to and fro most, and no where else but there.  Therefore betweene the two Tropikes, that is, in the middle Zone, is greatest increase, multiplication, generation, and corruption of things, which also wee finde by experience; for there is Sommer twice in the yeere, and twice Winter, so that they haue two Haruests in the yeere, and continuall Spring.  Seeing then the middle Zone falleth out so temperate, it resteth to declare where the hottest part of the world should bee, for we finde some places more hote then others.
