In the time of Santeul - Santolius, the international language was Latin, easily to understand by anyone.
Everyone latinised also his name.
A pity I forgot most of this language (I studied it, and also Greek, for 6 years in my youth and could easily read and write it when I was 18, but I changed my field of intrests to economics at that time), as a lot of information of historical facts can be found in those latin texts.
Maybe I should start to learn it again once on retirement
Best wishes for X-mas and a prosperous 2010
