"_Quadrijugis invectus equis," &c._ (Vol. ii., p. 391.).--These lines, in
which "veriis" and "antesolat" are, of course, misprints for "variis" and
"antevolat," apply with such peculiar exactness to Guido's celebrated
Aurora, at the Rospigliosi Palace, that I cannot but think the painting has
given rise to the lines. Besides, in the ancient mythology, the Horæ are
said to be _three_ in number, daughters of Jupiter and Themis, and one of
their offices was harnessing the horses of the Sun. It is unlikely,
therefore, that any classic author would mention them as being seven in
number.
