I think I am right in saying that Dr. John Dee's 'Speculum Unitatis', his defence of Roger Bacon, is lost? If so, then what is this a reference to in the Portheim library: http://www.archiwum.portheim.org/listarefPRAC.php?lexID=8027 Or was their copy lost during the Second World War? Thanks for any help you can provide, Paul |
