 There is much uncertainly as to when, where, why and by whom these works were created. No one answer to these questions will fit all of the treatises. Most scholars (e.g., Burkert 1972b, 40–44; Centrone 1990, 30–34, 41–44 and 1994) have chosen Rome or Alexandria between 150 BCE and 100 CE as the most likely time and place for these compositions, since there was a strong resurgence of interest in Pythagoreanism in these places at these times (see below). Thesleff’s view that the majority were composed in the third century BCE in southern Italy (1961 and 1972, 59) has found less favor. Centrone argues convincingly that a central core of the pseudepigrapha were forged in the first centuries BCE and CE in Alexandria, because of their close connection to Eudorus and Philo, who worked in Alexandria in that period (Centrone 2014a). For an overview of the Pythagorean pseudepigrapha see Centrone 2014a and Moraux 1984, 605–683.
