BUT
Unfortunately, by trying to get on their Coursera curse, https://www.coursera.org/learn/burgos-deciphering-secrets-medieval-spain/home/welcome I could see, from the very beginning, how information was oriented the same old Catholic way, but with modern informatics tools and on-line teachings: presenting a map where Castilla was suppose to occupy half Spain ( when all Christian kingdoms together just represent 10% of Spain), with no date indication. I just renounced to that course. Too bad.
