Various sources for the text of Philo have been either inadequately edited or overlooked more or less completely. This paper will report on some discoveries found in various manuscripts. First, the Coptos Papyrus of Philo, which contains De sacrificiis and Quis heres, contains many superior readings that were not reported in the 1893 edition by Scheil and thus are also not found in the Cohn-Wendland edition; some of these will be presented here. Second, there are some fragments from an otherwise unknown work that are found in the Oxyrhynchus Papyrus of Philo; these have been edited, but have been (it seems) almost entirely neglected. Third, from a known work a further reading that seems to be original is also found in the Oxyrhynchus Papyrus, which was erroneously edited at that place. Fourth, a few Greek fragments from De providentia 1, otherwise completely unknown in Greek (even to Eusebius), will be discussed.
