 There are fewer forged treatises in Pythagoras’ name than in the name of other Pythagoreans and they are a very varied group suggesting different origins. Callimachus, in the third century BCE, knew of a spurious astronomical work circulating in Pythagoras’ name (Diogenes Laertius IX 23) and there may have been a similar work forged in the second century (Burkert 1961, 28–42). A group of three books, On Education, On Statesmanship and On Nature, were forged in Pythagoras’ name sometime before the second century BCE (Diogenes Laertius VIII 6 and 9; Burkert 1972a, 225). Heraclides Lembus, in the second century BCE, knew of at least six other works in Pythagoras’ name, all of which must have been spurious, including a Sacred Discourse (Diogenes Laertius VIII 7). The thesis that the historical Pythagoras wrote a Sacred Discourse should be rejected (Burkert 1972a, 219). There was also a spurious treatise on the magical properties of plants and the Golden Verses, which are discussed further below (sect. 4.5). On the spurious treatises assigned to Pythagoras see Centrone 2014a, 316–318.
