§ 13.1. In regard to the =year of the birth= and the =year of the death= of the Redeemer no absolutely certain result can now be attained. The usual Christian chronology constructed by Dionysius Exiguus in the sixth century, first employed by the Venerable Bede, and brought into official use by Charlemagne, assumes the year 754 A.U.C. as the date of Christ’s birth, which is evidently wrong, since, in A.D. 750 or 751, Herod the Great was already dead. Zumpt takes the seventh, others the third, fourth, or fifth year before our era. The length of Christ’s public ministry was fixed by many Church Fathers, in accordance with Isaiah lxi. 1, 2, and Luke iv. 19, at one year, and it was consequently assumed that Christ was crucified when thirty years of age (Luke iii. 21). The synoptists indeed speak only of one passover, the last, during Christ’s ministry; but John (ii. 13; vi. 4; xii. 1) speaks of three, and also besides (v. 1) of a ἑορτὴ τῶν Ἰουδαίων.
§ 13.2. Among the non-biblical =witnesses to Christ= the earliest is probably a Syrian Epistle of =Mara= to his son Serapion, written, according to Cureton (“_Spicileg. Syriacum_.” Lond., 1855), about A.D. 73. The father, highly cultured in Greek wisdom but dissatisfied with it, writes from exile words of comfort and exhortation to his son, in which he places Christ alongside of Socrates and Pythagoras, and honours him as the wise King, by whose death the Jews had brought upon themselves the swift overthrow of their kingdom, who would, however, although slain, live for ever in the new land which He has given. To this period also belongs the witness of the Jewish historian =Josephus=, which in its probably genuine portions praises Jesus as a worker of miracles and teacher of wisdom, and testifies to His death on the cross under Pilate, as well as the founding of the church in His name. Distinctly and wholly spurious is the =Correspondence of Christ with Abgar=, Prince of Edessa, who entreats Christ to come to Edessa to heal him and is comforted of the Lord by the sending of one of His disciples after His ascension. This document was first communicated by Eusebius (_Hist. Eccl._, i. 13) from the Archives of Edessa in a literal translation from the Syriac, and is also to be found in the Syrian book _Doctrina Addæi_ (§ 32, 6). Of a similar kind are the apocryphal =Acta Pilati=, as well the heathen form which has perished (§ 22, 7), as the Christian form which is still extant (§ 32, 4). An =Epistle of Lentulus,= pretending to be from a Roman resident in Palestine on terms of intimacy with Pilate, containing a description of the appearance of Christ, is quoted, and even then as a forgery, by Laurentius Valla in his writing on the _Donation of Constantine_. Since in many particulars it agrees with the description of the person of Christ given in the Church History by Nicephorus Callisti (§ 5, 1), in accordance with the type then prevailing among Byzantine painters, it may fairly be regarded as an apocryphal Latin retouching of that description originating in the fifteenth century. At Edessa a picture of Christ was known to exist in the fourth century (according to the _Doctr. Addæi_), which must have been brought thither by the messengers of Abgar, who had picked it up in Jerusalem. During the fourth century mention is made of a statue of Christ, first of all by Eusebius, who himself had seen it. This was said to have been set up in Paneas by the woman cured of the issue of blood (Matt. ix. 20). It represents a woman entreating help, kneeling before the lofty figure of a man who stretches out his hand to her, while at his feet a healing herb springs up. In all probability, however, it was simply a votive figure dedicated to the god of healing, Æsculapius. The legend that has been current since the fifth century of the sweat-marked handkerchief of =Veronica=--this name being derived either from _vera icon_, the true likeness, or from Bernice or Beronice, the name given in apocryphal legends to the woman with the issue of blood,--on which the face of the Redeemer which had been wiped by it was imprinted, probably arose through the transferring to other incidents the legendary story of Edessa. On the occurrence of similar transferences see § 57, 5.
