“Immo age, et a prima dic, hospes, origine nobis
insidias,” inquit, “Danaum, casusque tuorum,
erroresque tuos; nam te iam septima portat                      1.755
omnibus errantem terris et fluctibus aestas.”

 

This time, the wanderer is Aeneas, who has been as without focus, as we learn in Aeneid 2 and 3, as Dido in the underworld.  This parallel may explain the color shift.  Dido was our blue wanderer, but I have chosen to maintain the color, even though it here pertains to Aeneas.  The olive green is, however, the signature of Aeneas-as-Apollo.  The mixed colors of “erroresque tuos” lead us back some dozen lines to the establishment of the moon and sun as key motifs in the story of Dido and Aeneas.
