Philo wrote a work entitled περὶ βίου Μωσέως: Vita Mosis, which is still extant, but is not mentioned in the catalogue of Eusebius. It contains a long description of the tabernacle, and consequently Schürer concludes that the work mentioned here by Eusebius (περὶ τῆς σκήνης) represents that portion of the larger work. If this be the case, it is possible that the section in the mss. used by Eusebius was detached from the rest of the work and constituted an independent book. The omission of the title of the larger work is doubtless due, as Schürer remarks, to the imperfect transmission of the text of Eusebius’ catalogue. See Schürer, p. 855.
