While overly confident, your response is not factually correct. Are you familiar with Francisco de Montejo, a Spanish conquistador who burnt innumerable Mayan historical documents etc?

The composition of these codices was at its peak hundreds of years earlier and zero survived the reciprocal annihilation that had not a trace of influence from the Spaniards who were under direct Arab colonial domination that was to last longer than any in the post columbian period.
