Annotations to James Joyce's Ulysses/Eumaeus/573

Annotations
haud ignarus malorum miseris succurrere disco   (Latin) Not at all unacquainted with misfortunes, I learn to succour the wretched. The narrator (Bloom?) has adapted a line (1:630) from Virgil's epic poem the Aeneid: Non ignara mali, miseris succurrere disco (Not unacquainted with misfortune, I learn to succour the wretched). Dido says this to Aeneas.
