was accufed with him of having murdered Germanicus,

lity of the emperor for her perfon. When Ihe faw her- 
felf freed from the accufation, llie abandoned her hulband 
to his fate. Subfervient in every thing to the will of Li¬ 
via, ihe, at her inlligation, became guilty of the greatell 
crimes, to injure the character of Agrippina. After the

felf ridiculous by his follies and his extravagance. He

became one of the moil fervile flatterers of Cleopatra and 
Antony. At the court of the Egyptian queen, he ap¬ 
peared in the character of a ilage-dancer; perfonated 
Giaucus, and painted his body of a green colour, dancing 
quite naked, only with a crown of green reeds on his 
head, while he had tied behind his back the tail of a large 
fea-fifli. This expofed him to the public derilion ; and, 
when Antony joined the reft of his friends in cenfuring 
him for his unbecoming behaviour, he deferted to Odta- 
vius, who received him with great marks of friendihip 
and attention. Horace has dedicated an Ode to him; 
and he deferved the honour, from the elegance of his let¬ 
ters, which are ftili extant, written to Cicero. He found¬ 
ed a town in Gaul, which he called Lugdunum. Pint, in
