The daughter of Titus Andronicus, bride of Bassianus, brother of
the Emperor of Rome. Being grossly abused by Chiron and Demetrius, sons
of Tamora, Queen of the Goths, the savage wantons cut off her hands and
pluck out her tongue, that she may not reveal their names Lavinia,
guiding a stick with her stumps, makes her tale known to her father and

In the play the word is accented Andronicus not Andronicus.
Italy; so called from Lavinia, daughter of Latinus and wife of
