its walls.

Such was the story of Dido which Venus related to AEneas and Achates.
Having concluded, she inquired in her turn who they were, from what
country they had come, and whither they were going. In reply AEneas
gave a brief account of his wanderings since the fall of Troy. Then
the goddess directed him to go into the city and present himself
before the queen, and she pointed to an augury in the sky--twelve
swans flying above their heads--which, she said, was a sign that the
ships they had supposed to be lost were at that moment sailing into
the harbor.

So saying Venus turned to leave them, when suddenly a marvelous change
took place in her dress and appearance, so that AEneas knew she was
his mother, and he cried to her to permit him to touch her hand and
speak with her as her son. The goddess, however, made no answer, but
she cast over Aeneas and his companion a thick veil of cloud so that
no one might see or molest them on their way. Thus rendered invisible,
they went towards the city. When they reached it they found a great
many men at work, some finishing the walls, others erecting great
buildings of various kinds. In the center of the town was a
magnificent temple of Juno.

Enriched with gifts, and with a golden shrine;
But more the goddess made the place divine.
On brazen steps the marble threshold rose,
And brazen plates the cedar beams enclose;
The rafters are with brazen coverings crowned;
The lofty doors on brazen hinges sound.
