Question: Who is the mother of the person under whom the entity from which Satyricon originated reached its greatest extent?

W. C. Firebaugh was the author of two works on the history of inns and taverns, and also of a fine English translation of Petronius's "Satyricon", the fragmentary realistic novel of low life under the Roman Empire. <SEP> The imperial period of Rome lasted approximately 1,500 years compared to the 500 years of the Republican era. The first two centuries of the empire's existence were a period of unprecedented political stability and prosperity known as the Pax Romana, or ``Roman Peace ''. Following Octavian's victory, the size of the empire was dramatically increased. After the assassination of Caligula in AD 41, the Senate briefly considered restoring the republic, but the Praetorian Guard proclaimed Claudius emperor instead. Under Claudius, the empire invaded Britannia, its first major expansion since Augustus. After Claudius' successor, Nero, committed suicide in AD 68, the empire suffered a series of brief civil wars, as well as a concurrent major rebellion in Judea, during which four different legionary generals were proclaimed emperor. Vespasian emerged triumphant in AD 69, establishing the Flavian dynasty, before being succeeded by his son Titus, who opened the Colosseum shortly after the eruption of Mount Vesuvius. His short reign was followed by the long reign of his brother Domitian, who was eventually assassinated. The Senate then appointed the first of the Five Good Emperors. The empire reached its greatest extent under Trajan, the second in this line. <SEP> the modern mother's day began in the united states, at the initiative of ann reeves jarvis in the early 20th century. this is not (directly) related to the many traditional celebrations of mothers and motherhood that have existed throughout the world over thousands of years, such as the greek cult to cybele, the roman festival of hilaria, or the christian mothering sunday celebration (originally a commemoration of mother church, not motherhood). however, in some countries, mother's day is still synonymous with these older traditions. <SEP> in 1729, nader shah, a chieftain and military genius from khorasan, successfully drove out and conquered the pashtun invaders. he subsequently took back the annexed caucasian territories which were divided among the ottoman and russian authorities by the ongoing chaos in iran. during the reign of nader shah, iran reached its greatest extent since the sassanid empire, reestablishing the iranian hegemony all over the caucasus, as well as other major parts of the west and central asia, and briefly possessing what was arguably the most powerful empire at the time. <SEP> Marcus Ulpius Traianus was born on 18 September 53AD in the Roman province of Hispania Baetica (in what is now Andalusia in modern Spain), in the city of Italica (now in the municipal area of Santiponce, in the outskirts of Seville). Although frequently designated the first provincial emperor, and dismissed by later writers such as Cassius Dio (himself of provincial origin) as "an Iberian, and neither an Italian nor even an Italiot", Trajan appears to have hailed on his father's side from the area of Tuder (modern Todi) in Umbria, at the border with Etruria, and on his mother's side from the Gens Marcia, of an Italic family of Sabine origin. Trajan's birthplace of Italica was founded as a Roman military colony of "Italian" settlers in 206BC, though it is unknown when the Ulpii arrived there. It is possible, but cannot be substantiated, that Trajan's ancestors married local women and lost their citizenship at some point, but they certainly recovered their status when the city became a municipium with Latin citizenship in the mid-1st century BC.
