As early as 1666 Leibniz was able to compose "A Conjecture Why It Seems That Anaxagoras Could Have Said That Snow Is Black" (A II, 1, 4-5). Later, as a librarian, he became extraordinarily well read and knew most of what was preserved from Anaxagoras' views. However his references usually come indirectly by quoting a critical remark made by Socrates in Plato's Phaedo.
Today it seems easy to find many similarities between Leibniz' Monadology and Anaxagoras' philosophy. Who was the first to note and/or comment in print such a connection?
