Apocryphal book on Hasmonean reigning families - I Maccabees then II Maccabees

From Edgar Goodspeed's page of introduction in The Apocrypha: An American Translation (1938) --

This book (First Maccabees) is the prime account of the Jewish war of independence fought against Antiochus Epiphanes; it covers the years 167 to 134 B.C. (before Christian era)  Its author was apparently an eyewitness of the events and a devoted partisan of the Maccabees.  But he is careful and competent as well as patriotic and devout.  Although written in Hebrew, the book exhibits the characteristics of Hellenistic historiography in its emotionalism, partisanship, and use of documents; but it is nevertheless a mature and reliable work, and of high excellence both as history and as literature.
The dates in I and II Maccabees are usually given according to the Seleucid era, and can be converted to our reckoning by equating year 1 of that era to 312/311 B.C.
