When with his golden Horns, in full Career, 
The Bull beats down the Barriers of the Year; 
And Argos , and theD^, forfake the Northern

for Heinfius’s Correction of adverfo , it we compare 
the Diction here with Ovid's,

The Bull's oppoftng Horns obftrud the Way. 
The Inftru&ions Virgil gives in the fame Place, as 
to Husbandry, are belt underltood from this new

And the bright Gnojian Diadem downward bend.
