Greed for money and power in benjonson alchemist

Gold is the result of successful alchemy, though the goal remains aspirational. It plays a large part in the play as the motivation for just about everything that happens. The gulls are all greedy for gold in order to achieve their dreams, and they are therefore greedy for the Philosopher's Stone. The conmen, inversely, are greedy for the gold they make by tricking the gulls into believing that they will eventually be rich.
