Epiphanius has preserved a certain "Epistle to Flora" ascribed to Ptolemseus, in which, it is contended, there are "several quotations from Matthew, and one from the first chapter of John."(1) What date must be assigned to this Epistle? In reply to those who date it about the end of the second century, Tischendorf produces the evidence for an earlier period to which he assigns it. He says: "He (Ptolemæus) appears in all the oldest sources

as one of the most important, most influential of the disciples of Valentinus. As the period at which the latter himself flourished falls about 140, do we say too much when we represent Ptolemæus as working at the latest about 160? Irenæus (in the 2nd Book) and Hippolytus name him together with Heracleon; likewise pseudo-Tertullian (in the appendix to De Præscriptionibus Hæreticorum) and Philastrius make him appear immediately after Valentinus. Irenæus wrote the first and second books of his great work most probably (hochst warscheinlich) before 180, and in both he occupies himself much with Ptolemæus."(1) Canon Westcott, beyond calling Ptolemæus and Heracleon disciples of Valentinus, does not assign any date to either, and does not of course offer any further evidence on the point, although, in regard to Heracleon, he admits the ignorance in which we are as to all points of his history,(2) and states generally, in treating of him, that "the exact chronology of the early heretics is very uncertain."(3)
Let us, however, examine the evidence upon which Tischendorf relies for the date he assigns to Ptolemæus. He states in vague terms that Ptolemæus appears "in all the oldest sources" (in alien den altesten Quellen) as one of the most important disciples of Valentinus. We shall presently see what these sources are, but must now follow the argument: "As the date of Valentinus falls about 140, do we say too much when we represent Ptolemæus as working at the latest about 160?" It is obvious that there is no evidence here, but merely assumption, and the manner in which the period "about 160" is begged, is a clear admission that there are no certain data. The year
might with equal propriety upon those grounds have been put ten years earlier or ten years later. The deceptive and arbitrary character of the conclusion, however, will be more apparent when we examine the grounds upon which the relative dates 140 and 160 rest. Tischendorf here states that the time at which Valentinus flourished falls about a.d. 140, but the fact is that, as all critics are agreed,(1) and as even Tischendorf himself elsewhere states,(2) Valentinus came out of Egypt to Rome in that year, when his public career practically commenced, and he continued to flourish for at least twenty years after.(3) Tischendorf s pretended moderation, therefore, consists in dating the period when Valentinus flourished from the very year of his first appearance, and in assigning the active career of Ptolemseus to 160 when Valentinus was still alive and teaching. He might on the same principle be dated 180, and even in that case there could be no reason for ascribing the Epistle to Flora to so early a period of his career. Tischendorf never even pretends to state any ground upon which Ptolemæus must be connected with any precise part of the public life of Valentinus, and still less for discriminating the period of the career of Ptolemæus at which the Epistle may have been composed. It is obvious that a wide limit for date thus exists.
After these general statements Tischendorf details the only evidence which is available. (1) "Irenæus (in the 2nd Book) and Hippolytus name him together with Heracleon; likewise (2) pseudo-Tertullian (in the
appendix to De Præscriptionibus Hæreticorum) and Philastrius make him appear immediately after Valentinus," &c. We must first examine these two points a little more closely in order to ascertain the value of such statements. With regard to the first (1st) of these points, we shall presently see that the mention of the name of Ptolemseus along with that of Heracleon throws no light upon the matter from any point of view, inasmuch as Tischendorf has as little authority for the date he assigns to the latter, and is in as complete ignorance concerning him, as in the case of Ptolemseus. It is amusing, moreover, that Tischendorf employs the very same argument, which sounds well although it means nothing, inversely to establish the date of Heracleon. Here, he argues: "Irenæus and Hippolytus name him (Ptolemæus) together with Heracleon;"(l) there, he reasons: "Irenæus names Heracleon together with Ptolemæus,"(2) &c. As neither the date assigned to the one nor to the other can stand alone, he tries to get them into something like an upright position by propping the one against the other, an expedient which, naturally, meets with little success. We shall in dealing with the case of Heracleon show how untenable is the argument from the mere order in which such names are mentioned by these writers; meantime we may simply say that Irenæus only once mentions the name of Heracleon in his works, and that the occasion on which he does so, and to which reference is here made, is merely an allusion to the Æons "of Ptolemseus himself, and of Heracleon, and all the rest who hold these views."(3) This phrase might have been used, exactly as it stands, with
