Re: Heliocentric Universe -- 54v (Beinecke)

["Dana F. Scott" <dfscott@xxxxxxxxxxx>]

Dear Robert,
       Thank you for your comments. Your observations are well taken. No
doubt Aristarkhos deserves considerable credit for his original genius.
Copernicus was familiar with Aristarkhos's phenomenal observations on
astronomy. There are certain other reasons why I find Copernicus
interesting in relation to the VMS. Copernicus studied at Bologna and
lectured at Rome. And later Galileo, who had studied under Andreas
Cesalpino at Pisa, was influenced by Copernicus. Mine is but one
individual's observation, but I find considerable evidence to suggest
that the VMS evolved somewhere between Bologna, Rome, Pisa, and perhaps
Florence around the time (say 16th century, second half?) that these
great natural philosophers of the Renaissance shared their thoughts and
dicoveries with the rest of the world.
