Nero’s mother, Agrippina the younger, daughter of Germanicus and of Agrippina the elder, was assassinated at Nero’s command in 60 a.d. in her villa on Lake Lucrine, after an unsuccessful attempt to drown her in a boat so constructed as to break to pieces while she was sailing in it on the lake. His younger brother Britannicus was poisoned by his order at a banquet in 55 a.d. His first wife Octavia was divorced in order that he might marry Poppæa, the wife of his friend Otho, and was afterward put to death. Poppæa herself died from the effects of a kick given her by Nero while she was with child.
