Nero Claudius Drusus. The poem opens by advising Livia not to try to hide her sad emotions and contrasts Drusus' military virtue with his death. Drusus' funeral and the tributes of the imperial family are described as are his final moments and Livia's lament over the body, which is compared to birds. The laments of the city of Rome as it greets his funeral procession and the gods are mentioned, and Mars from his temple dissuades the Tiber river from quenching the pyre out of grief. Grief is expressed for his lost military honors, his wife, and his mother. The poet asks Livia to look for consolation in Tiberius. The poem ends with an address by Drusus to Livia assuring him of his fate in Elysium. Although this poem was connected to the Elegiae in Maecenatem, it is now thought that they are unconnected. The date of the piece is unknown, but a date in the reign of Tiberius has been suggested because of that emperor's prominence in the poem.

Nux ("The Walnut Tree") This short poem in 91 elegiac couplets is related to Aesop's fable of "The Walnut Tree" that was the subject of human ingratitude. In a monologue asking boys not pelt it with stones to get its fruit, the tree contrasts the formerly fruitful golden age with the present barren time, in which its fruit is violently ripped off and its branches broken. In the course of this, the tree compares itself to several mythological characters, praises the peace that the emperor provides and prays to be destroyed rather than suffer. The poem is considered spurious because it incorporates allusions to Ovid's works in an uncharacteristic way, although the piece is thought to be contemporary with Ovid. Somnium ("The
