In our discussions of the "Aetius / Placata" volume we see numbers of references to "Metrodorus" - some of which may be Metrodorus of Chios (a Democritean and predecessor to Epicurus) and some of which are Metrodorus of Lampsacus (one of Epicurus' primary followers). There are huge differences between the two, including Metrodorus of Chios following Democritus' lead toward skepticism and "nothing is real except atoms and void" which Epicurus (and therefore presumably Metrodorus of Lampsacus) vigorously rejected.
It's going to be easy to confuse these two together, so this thread is intended to provide a place where we can post about how they differ and/or resemble each other.
Thanks to Bryan for pointing this out:
When Aetius mentions Metrodorus, it seems he is typically referring to Metrodorus of Chios:
