He wrote moral essays, philosophical letters, physical treatises, and tragedies.

Of the last, the best are HERCULES FURENS, PHAEDRA, and MEDEA.
GALBA (68-69) .-- OTHO (69) .-- VITELLIUS (69).
GALBA entered the city as a conqueror, without much trouble, but on account of his parsimony and austerity he soon became unpopular, and was murdered by his mutinous soldiers fifteen days after he reached Rome.
He belonged to an old patrician family, and his overthrow was sincerely regretted by the better element in the city.
OTHO, the first husband of Poppaea, and the leader in the insurrection against Galba, was now declared Emperor.

No sooner did the news of his accession reach Gaul than VITELLIUS, a general of the army of the Rhine, revolted.

Otho marched against the rebels, was defeated, and committed suicide after a reign of three months.
VITELLIUS had been a good soldier, but as a ruler he was weak and incapable.

He was killed after a reign of less than a year, during which he had distinguished himself by gluttony and vulgar sensuality..
