About two weeks ago I was contacted about participating in a conference next year at the University of Groningen. In 2014 they are celebrating their 400th anniversary so it seems appropriate it relate to something else from 1614. In that year, Johannes Kepler published his tome on chronology, arguing that Jesus was born several years earlier than was the tradition in his time (on Dec 25 in 1 BC). In that book, he also talked about the Star of Bethlehem, and this is the apparent link for this conference.
