I make no comment on this inclusion, sent in by Gary Gilligan, a link to a piece that asks if Hannibal really crossed the Alps with an army – and some elephants. The gist of the piece is a bit of grist, and that is that historians accept he did but when it comes to events in the Bible such as the Exodus they cast doubt on the authenticity of such things. See http://anebooks.blogspot.com/2007/05/hannibal-and-alps.html. One aspect missing is that most of the Roman period was warm – warmer than today. Therefore, the Alps would have been relatively easy to traverse – without encountering large glaciers.
