The Star of Bethlehem is known to almost everybody, whatever their personal faith - be it through the Nativity story told in Matthew’s Gospel or through art and material culture where the depiction of the Star has played a hugely important role for centuries. Church Fathers and scholars alike have debated the ‘when’ and ‘what’ for almost as long, resulting in very different interpretations. However, what had been missing so far was a multi-disciplinary approach.
