Aratus therefore, I think, thews at leaf!, that the 
Dog dar was not then of the lame colour as other 
dars: and, as Cicero turns it rutilus , it appears he 
either underftood the word to mean red, or knowings 
by his own view it was fo, thought it the proper inter- 
pretation ; for rutilus is ufed of what is reddilh, and 
often of the red glare of a lire, or the dawn, as be- 
low : 
rutilum vomit ille cruorem, Ovid. Met.V. 33*. 
Promiffje et rutilatae comas. Livy. XXXVIII. 17. 
Arma inter nubem, ceeli in regione ferena. 
Virg. Mneid. VIII. 728,. 
Per fudum rutilare vident. 
Sin maculae incipient rutilo immifcerier igni. 
Georg. I. 454, 
Auroram rutilare procul cerno. 
, Varro, de Ling. Lat. VI. 5V 
Rubra , in Horace, will, I think, bear no other 
fenfe than red, or elfe it is the heat he there chiefly 
fpeaks of : and though, I think, Latin authors con- 
found Canicula , fome ufing the word for Sirius , 
others for Procyon ; yet it plainly appears, that 
Sirius is here meant, fince Horace always calls it 
Canicula, and never ufes the word Sirius : but Ara- 
tus and Ptolemy leave no room to doubt what dar it 
was, being exprefly fpeaking about the Dog dar. 
Seneca fays, the rednefs was fo drong as to exceed 
that of Mars, to which no dar now approaches. 
None of the notes on Seneca clear up this matter: 
Fromondus, indeed, obferved the place, and de- 
, dared his adonilhment at it 5 but does not attempt 
tO;
