CHAPTER VII. 
Of the Discovery of the Quarry that produced the Stones for erecting the 
Temple of Diana at Ephesus. 
SHALL make a little digression to relate how this quarry was discovered. A shepherd 
named Pixodorus frequently wandered about the place: and at the time when the citizens 
of Ephesus were considering of building the Temple of Diana with marble, and were debating 
whether to have that of Paros, Proconnesus, Heraclea, or Thasos, Pixodorus drove his flock 
there to feed. It happened that two rams encountering missed each other; and one struck 
his horn with violence against a stone, a shiver of which flying off, appeared to be exceedingly 
white. Pixodorus, it is faid, then left his sheep in the mountains, and ran speedily with the 
shiver to Ephesus, where he related the circumstance. Upon this, honours were immediately 
decreed him; his name was changed from Pixodorus to Evangelus: and even at this day the 
magistrate goes every month to the place, and sacrifices to him; being, if he omit it, liable to 
a penalty. 
CHAPTER VIII. 
Of the straight and circular Motions of Machines for raising of Weights. 
LHAVE briefy explained what I judged was necessary concerning tractorial machines, the 
movements and powers of which depend on two principle,different and disimilat from each 
other, but so agreing, that the operation is perfected by both; one is rectinearity, which 
the Greeks calleuthbian; and the other is cicularity, which they call gelbten. But, in truth, 
neiher the redilinear motion vithout the circular, nor the circular motion vithout the rectr- 
linear, can be effectual for raising of weights. This I fhalleplain, that it may be more 
intelligible.
