Caius T. Suetonius

Augustus Caesar, was the first Emperor. He is considered as the founder of Rome Empire. "The name of Augustus was the title of honour given by the Romans to the emperor Caius Julius Cassar Octavianus, or, as he was originally designated, Caius Octavius. This title was intended to be hereditary in his family, but all the succeeding Caesars or emperors of Rome continued to adopt it, long after they had ceased to be connected with the first Augustus by blood. The era of Augustus formed an illustrious epoch in Roman history, and was distinguished for its splendid attainments in arts and arms, and more especially in literature. The Romans in later times looked back to the age of Augustus with great complacency, as the most prosperous and the most distinguished in their annals. (Encyclop dia Britannica)

Caligula was Emperor of Rome from A.D. 37 to 41. He was the youngest son of Germanicus (nephew of Tiberius) by Agrippina, and was born August 31, A.D. 12, at Antium, and was educated in the camp, where the soldiers gave him the nickname Caligula, from the military boots (calig ) which he wore... "The profusion of this emperor, during his short reign of three years and ten months, is unexampled in history. In the midst of profound peace, without any extraordinary charges either civil or military, he expended, in less than one year, besides the current revenue of the empire, the sum of 21,798,875 sterling, which had been left by Tiberius at his death..."
