You're right, for some reason I was thinking there was a generation gap there, but it's true that Aristotle did his own teaching also in Athens only a bit later. But I think my point survives, since what we have of Aristotle's works are thought to actually be notes compiled by his students- not intended as finished publications at all. Whether they were released to the public in his time seems to be unknown- there's a story about them being locked in a cellar for a generation before being rediscovered, but apparently that's apocryphal.
