Of other 5th-century sources, Aristophanes is obviously a caricaturist, pseudo-Xenophon (de republica Atheniensium) a mere party pamphleteer.
The latter were no doubt deliberately exaggerated, and yet a comparison between the head of Fox in Sayer's plate "Carlo Khan's triumphal entry into Leadenhall," and in Abbot's portrait, shows that the caricaturist did not depart from the original.
He found continued scope for his powers as a political caricaturist in the columns of the Anti-Jacobin, a weekly paper which he founded in connexion with George Canning and William Gifford.
An orator of a business-like, straightforward type, cool and hard-hitting, his spare figure, incisive features and single eye-glass soon made him a favourite subject for the caricaturist; and in later life his aggressive personality, and the peculiarly irritating effect it had on his opponents, made his actions and speeches the object of more controversy than was the lot of any other politician of his time.
