of Stuuica's Commentary in which it occurs is inserted in 



". tinitfiiml Translations ( 1061), which contains, 



.nslatioii <>t' the Dinlogi del Sistemi, translations of certain tracts 



on the religious inu-tmu involved in the Copernican controversy. I am 



-'tut is an odd expression for anything except a verse 



in the Iiihl.\ that M. r.diiillet is not right in thinking that the reference is 

 to what is said of Pliilolaus by Plutarch, De Placit. Phil., which (as Apelt 

 has remarked) Copernicus has always mistranslated, confounding the cen- 

 tral tire, the >rat of the gods, with the sun. See Apelt's Reformation of 

 Astronomy, 1S52. p. 128. 



Apelt altogi-ther agrees with Bacon as to the complete originality of Co- 

 pernicus. aMl. apparently forgetting what is said of Aristarchus by Archi- 

 medes and <>thi-r<, says that the idea of the annual movement of the earth 

 sprang out of the mind of Copernicus, as Minerva from the head of Ju- 

 piter. But yet, as Humboldt has remarked, he may have been acquainted 

 with the doctrine of Aristarchus. See C<>*>n<>$, vol. ii. p. 349. Bacon was 

 not, or he would not have said that the immobility of the sun was, " ex- 



!>," a wholly new doctrine. 



A third h\] ISaron's meaning is that he refers to some pas- 



sage in which tlx- sun i> spoken of as rd /jaov, as Boeckh has pointed out 

 in hi- ca ultera de Plntonico Systemate. &e. The sun 



is sometin -f, O M musical grounds, and sometimes spoken of as 



fteoov TTUVTUV, simply because it occupies a middle place among the plan- 

 Tt in the Placit. Phil.; and it is perhaps to this 



that i ' !ii]i;in- Martin, Ettuhs sur le Timee, vol. ii. pp. 103. 



and 128. I have not seen Gruppe's recent work on the Cosmical System 

 of th The notion that Plato was the first proposer of the Coper- 



T unfounded. According to Apelt, Gruppe re- 

 lies on a pa->age in the seventh book of the De Leyibus.
