Some time after Addison's death, in 1719, a quarrel took place between Tickell, his literary executor, and Steele.

Tickell seemed to insinuate that Steele had not sufficiently acknowledged his obligations to Addison, and Steele, in an angry retort, called Tickell the "reputed translator" of the first Iliad, and challenged him to translate another book successfully.

The innuendo shows that Steele, who certainly had some means of knowing, was willing to suppose that Tickell had been helped by Addison.

The manuscript of Tickell's work, which has been preserved, is said to prove this to be an error, and in any case there is no real ground for supposing that Addison did anything more than he admittedly told Pope, that is, read Tickell's manuscript and suggest corrections.
To argue seriously about other so-called proofs, would be waste of time.
They prove nothing except Pope's extreme anxiety to justify his wild hypothesis of a dark conspiracy.

Pope was jealous, spiteful, and credulous.
