'The absence of the mention of an historical event in any given document proves nothing.There may be a perfectly legitimate reason for an incident not being recorded among the documents of antiquity, no matter how dramatic it was.The histories of the ancient world were limited in number and in scope.Roman records, for example, dealt principally with matters of interest to the political fortunes of the empire, rather than with isolated tragedies in remote countries that were under the imperial control....
While it is true that Josephus provides considerable data relative to Herod the Great (47-4 B.C.)—even numerous despicable deeds—it likewise is the case that his writings are

Second, it is not correct to say that history ignored this horrible event.It is recorded in the Gospel of Matthew, and Matthew’s narrative is a reliable first century document. It is neither an honest nor legitimate approach to history to simply eliminate this record because it is in the New Testament. Critics must not be allowed to choose only those sources that meet their personal agenda' (
