The fate of two of them cannot fail to impress the student of the history of the ruins of Rome. The pedestal of Agrippina the elder, daughter of Agrippa, wife of Germanicus, and mother of Caligula, and that of her eldest son Nero, were hollowed out during the Middle Ages, turned into standard measures for solids, and as such placed at the disposal of the public in the portico of the city hall. The pedestal of Nero perished during the renovation of the Conservatori Palace at the time of Michelangelo; that of Agrippina is still there. The fate of this noble woman is described by Tacitus in the sixth book of the Annals; she was banished by Tiberius to the island of Pandataria, now called Ventotiene, where she spent the last three years of her life in solitude and grief. In 33 A. D.--the most memorable date in Christian chronology--she either starved herself to death voluntarily, or was starved by order of her persecutor. On hearing of her death the emperor eulogized his own clemency, because, instead of strangling the princess and exposing her body on the Gemonian steps, he had allowed her to die a peaceful death in that island. No honors were paid to her memory, but as soon as Caligula succeeded Tiberius in the government of the empire, he sailed to Pandataria, collected the ashes of his mother and relatives, and ultimately placed them in the mausoleum. The cippus represented in the illustration below is manifestly the work of Caligula, because mention is made on it of his accession to the throne. The hole excavated in it in the Middle Ages is capable of holding three _hundred_ pounds of grain, as shown by the legend RVGIATELLA DE GRANO, engraved in Gothic letters above the municipal coat of arms. The three armorial shields below belong to the three syndics, or conservatori, by whose authority the standard measure was made. Another inscription, engraved in 1635 on the opposite side, says: "The S. P. Q. R. pay honor to the memory of the noble and courageous woman who voluntarily put an end to her life" (and here follows a witticism of doubtful taste on the _bread_ which she denied herself, and on the _breadstuffs_, for the measurement of which her tomb had been used). [Illustration: The Cippus of Agrippina the Elder, made into a measure for grain.] The other cippi found in the _ustrinum_ mention four other children of Germanicus, among them Caius Cæsar, the lovely child who was so much beloved by Augustus, and so deeply regretted by him. A statue representing the youth with the attributes of a Cupid was dedicated by Livia in the temple of the Capitoline Venus, and another one was placed by Augustus in his own bedroom, on entering and leaving which he never missed kissing the cherished image.
