<br/><br/> The numerous references made by John of Murs to Alphonse of Castile in the Expositio show that the corpus to which he points had a material existence. It can be distinguished from the latin and castellan alphonsine astronomies and probably, at least on some points, it didn’t expose a single coherent astronomical theory but rather a plurality of opinions.
