Page "Boudica" Paragraph 22

According to Tacitus in his Annals, Boudica poisoned herself, though in the Agricola which was written almost twenty years prior he mentions nothing of suicide and attributes the end of the revolt to socordia (" indolence "); Dio says she fell sick and died and then was given a lavish burial ; though this may be a convenient way to remove her from the story.

Considering Dio must have read Tacitus, it is worth noting he mentions nothing about suicide ( which was also how Postumus and Nero ended their lives ).
