Decided to do this for the sake of completeness.

 

*The intro is actually funny, something lacking in the later books

 

*”No spell yet devised enables wizards to fly unaided in human form.” Oh dear, continuity. Admittedly Voldemort may have invented the spell, but what’s the point of him doing so, apart from looking cool? Maybe to escape an anti-disApparition jinx, but there must be easier ways. And if “Levitation is commonplace”, why does no-one do it, given that it would be awesome to float everywhere?

 

*Given that wizards use other medievalisms, why were their brooms so rubbish in the Middle Ages? 

 

*”By the twelfth century, wizards had learned to barter services” - about 9,000 years behind Muggles, then.

 

*I speak Irish, and “Aingeingein” does not resemble an Irish word.

 

*Saxon language in the eleventh century? Unlikely, Old English (Anglo-Saxon) was already becoming Middle English by that time.

 

*The tale of Gunhilda and Goodwin shows us that domestic violence has a history far predating H&R. Isn’t it funny when a woman assaults a man?

 

*The flying gravel is funny.

 

*So by rule #6 Harry cheated with the Patronus in PoA! 

 

*The woman-hit-man-funny theme recurs in the Harpies’ entry.
