The Poet well perceived that I was wholly
Bewildered at the chariot of the light,
Where 'twixt us and the Aquilon it entered.

Whereon he said to me: "If Castor and Pollux
Were in the company of yonder mirror,
That up and down conducteth with its light,

Thou wouldst behold the zodiac's jagged wheel
Revolving still more near unto the Bears,
