Anecdotes
Suetonius was the private secretary of the emperor Hadrian, in charge of his correspondence (ab epistulis). This position gave him privileged access to the imperial archives, which explains the wealth of details and documents he cites in his biographies.
According to his contemporary and friend Pliny the Younger, Suetonius was a reserved man of study, almost shy. Pliny even intervened with the emperor Trajan to obtain a legal privilege for him, and helped him acquire a small country estate.
Suetonius is said to have been dismissed from his post at court for showing disrespect to the empress Sabina, Hadrian's wife. The historian Spartianus (Historia Augusta) reports this disgrace, which put an end to his career as a senior official.
In the 'Lives of the Twelve Caesars', Suetonius does not limit himself to great political deeds: he describes the physical appearance of the emperors, their quirks, their favorite phrases and their vices. It is he who reports the famous 'Make haste slowly' (festina lente) dear to Augustus.
It is thanks to Suetonius that we know the legend of the last words of several emperors, such as the 'Qualis artifex pereo' ('What an artist dies with me!') attributed to the dying Nero. These intimate details have made his work a treasure trove of quotations for the centuries that followed.
Primary Sources
He often repeated these maxims: “Make haste slowly,” and “A cautious commander is better than a rash one,” to show that one must act with as much promptness as caution.
He kept repeating that so great an artist was about to perish with him: *Qualis artifex pereo!*
When he saw that he was surrounded on all sides by daggers aimed at him, he wrapped his head in his toga and at the same time covered the lower part of his body with his left hand.
Suetonius Tranquillus, a man of the greatest merit, wishes to buy a small estate that one of your friends, it is said, is putting up for sale.
He removed from their posts Septicius Clarus, the praetorian prefect, and Suetonius Tranquillus, his secretary for correspondence, along with many others, because they had behaved toward his wife Sabina, in their private dealings, with less reserve than the respect due to the court demanded.
