On the day of the marriage Silanus committed suicide, having up to that time prolonged his hope of life, or else choosing that day to heighten the popular indignation. His sister, Calvina, was banished from Italy. Claudius further added that sacrifices after the ordinances of King Tullius, and atonements were to be offered by the pontiffs in the grove of Diana, amid general ridicule at the idea of devising penalties and propitiations for incest at such a time. Agrippina, that she might not be conspicuous only by her evil deeds, procured for Annæus Seneca a remission of his exile, and with it the prætorship. She thought this would be universally welcome, from the celebrity of his attainments, and it was her wish too for the boyhood of Domitius to be trained under so excellent an instructor, and for them to have the benefit of his counsels in their designs on the throne. For Seneca, it was believed, was devoted to Agrippina from a remembrance of her kindness, and an enemy to Claudius from a bitter sense of wrong.
