Reading and Those Pesky Historical Errors

I read historical mysteries until I come to the first factual error. When I find one, and I’m sure I miss a lot of them, I evaluate the book and decide if I should go on. If I stop reading it is never because of the error but because plot, character or action have not caught me up in the story enough to overlook it.
Take my most recent read. The author knows the “school” history cold, kings, dates, outcomes of battles, political intrigue. The author has no notion of how people lived. There were many, many errors of daily life, some laughable. The author extols the virtues of pure bred dogs, black as a color of mourning for the middle class, and pepper used by a poor thief to distract his victims while he picks their pockets. While I am sure farmers bred best to best, the idea of scientific breeding and breed registers didn’t come along til late 18th early 19th century. Black was a color worn by rich people because the dye degraded the cloth and faded easily. Not practical for people who had to make clothing last. If the thief could have afforded pepper, he would have made more as a pepper merchant than as a cut purse.
Did I stop reading? No. The book was a rousing adventure story with winning characters and some nice scenes of court intrigue. Would I pick up another by this author? Probably not.
