Incest of unequal gravity: the "incestus iuris gentium," which was applied to both Romans and non-Romans in the Empire, and the "incestus iuris civilis," which concerned only Roman citizens. Therefore, for example, an Egyptian could marry an aunt, but a Roman could not. Despite the act of incest being unacceptable within the Roman Empire, Roman Emperor Caligula is rumored to have had sexual relationships with all three of his sisters (Julia Livilla, Drusilla, and Agrippina the Younger). Emperor Claudius, after executing his previous wife, married his brother's daughter Agrippina the Younger, and changed the law to allow an otherwise illegal union.
Agrippina condotta a morire or Dunque sarà pur vero Agrippina condotta a morire or Dunque sarà pur vero Agrippina condotta a morire or Dunque sarà pur vero, HWV110, is a dramatic secular cantata for soprano, two violins and continuo, composed by Georg Frideric Handel while he was in Italy, at some time between 1707 - 08. The anonymous text depicts Roman empress Agrippina the Younger on the way to her execution, which was ordered by her son, the emperor Nero, whom she had schemed to put on the throne. The title of the cantata, which is approximately fifteen minutes in length, may be translated as "Agrippina condemned to die".
