Two Alterations of Virgil in Chaucer's Dido

It is well known that Chaucer in his Legend of Dido allows himself considerable freedom in retelling the story found in Virgil and Ovid. This is not strange, since his purpose was to celebrate Dido, not Aeneas; he had to show that Dido was true, Aeneas false. His injunction was to tell Of Gode Wemen, maidenes and wyves, That were trewe in lovinge al hir lyves; And telle of false men that hem bitrayen. His added details are therefore carefully and subtly chosen with a view to arousing sympathy for Dido and blackening the at best somewhat dingy character of Aeneas.
