ζητήματα καὶ λύσεις: Quaestiones et solutiones. According to Schürer (ibid. p. 836 sq.), a comparatively brief catechetical interpretation of the Pentateuch in the form of questions and answers, embracing probably six books on Genesis and five on Exodus, and forming the first great group of writings upon the Pentateuch. So far as Eusebius seems to have known, they covered only Genesis and Exodus, and this is all that we are sure of, though some think that they included also the remainder of the Pentateuch. About half of his work (four books on Genesis and two on Exodus) is extant in an Armenian version (published by Aucher in 2 vols., Venet. 1822 and ’26, and in Latin by Ritter, vols. 6 and 7 of his edition of Philo’s works); and numerous Latin and Greek fragments still exist (see Schürer, p. 837 sqq.).
