Invehitur curru Phrygias turrita per urbes.
The Great Mother is represented in works of art as wearing a crown of towers. An explanation is given in Ovid's Fasti (iv. 219), a work which Wordsworth seems to have had in his thoughts throughout this stanza.
At cur turrifera caput est onerata corona?
An primis turres urbibus illa dedit?"
(W. A. Heard.)
