Every witness to Hornachos’s history is demonstrably untrustworthy

Evidence

What makes it so difficult to get to the bottom of what was going on in Hornachos in the final period is that all the individuals or groups who played a part in this very involved drama can be demonstrated not to be trustworthy, so that all evidence is suspect, and all motivation probably underhand. This goes for both sides, Christians and Muslims alike. — L. P. Harvey, Muslims in Spain, 1500 to 1614, 1703
