Among Roman writers of the period that dealt with general affairs were Asinius Pollio, the friend of Herod, and Titus Livius, who, under the name of Livy, has become the standard Latin historian for schoolboys. Josephus refers to both of them as well as to Timagenes, Posidonius, and Polybius; but as there is no reason to think that he ever tried to master the earlier authorities, it is probable that he knew them only so far as they were reproduced in his immediate sources and his immediate predecessors. The two writers whom he quotes repeatedly and must have studied are Strabo of Amasea (in Pontus) and Nicholas of Damascus. Strabo was an author of remarkable versatility and industry. Besides his geography, the standard work of ancient times on the subject, he wrote in forty-seven books a large historical work on the period between 150 (where Polybius ended) and 30 B.C.E. Nearly the whole of it has disappeared, but we can tell from Josephus' excerpts that he appreciated the Jews and their religion as did few other pagans of the time. He dealt, too, at considerable length with the wars of the Hasmonean kings against the Seleucids, and he is one of the authorities cited by Josephus for the period between the accession of John Hyrcanus and the overthrow of Antigonus II by Herod. The Jewish historian follows still more closely, and in many places probably reproduces, Nicholas, who was the court historian of Herod. Nicholas was a man of remarkable versatility. He played many parts at Herod's court, as diplomatist, advocate, and minister. He was a poet and philosopher of some repute, and he wrote a general history in forty-four books. In the first eight books he dealt with the early annals of the Assyrians, the Greeks, the Medes, and the Persians. Josephus, who took him for his chief guide after the Bible, often reproduces from him comparative passages to the Scripture story which he is paraphrasing. And for the later period of the _Antiquities_, from the time of Antiochus the Great (ab. 200 B.C.E.), he depends on him largely for the comparative Hellenistic history, which he brings into relation with the story of the Hasmoneans. When he comes to the epoch of Herod, the disproportionate fulness, the vivacity, and the dramatic power of the narrative in books XIV-XVI of the _Antiquities_ are due in a large measure to the historical virtues of the court chronicler. We can tell how far this is the case by the immediate and marked deterioration of the narrative when Josephus proceeds to the reigns of Archelaus and Agrippa--where Nicholas failed him.
