Who is trimalchio? in chapter 7 of the great gatsby

Trimalchio is a character that appears in Satyricon by Petronius (first century AD), and is also mentioned in the Great Gatsby (the beginning of Chapter 7).

Explanation:

Trimalchio and Gatsby have a lot in common. They were both poor (Trimalchio being a freed slave), and as they manage to acquire certain wealth, they both falsely pretend that they actually belong to the rich world. Trimalchio does so by dressing up, while Gatsby tries to impress people around him by throwing parties. In Chapter 7, the writer indicates that "Gatsby's career as Trimalchio was over", which means that Gatsby is no longer throwing parties and trying to prove his worth to those around him.
