This is a collected work of fiction. All events portrayed in this book are fictitious and any resemblance to real people or events is purely coincidental.
From the introduction:
Edward John Trelawny, whom I used as a character in my story “A Time to Cast Away Stones,” was a real historical person …
From the author’s note to “A Time to Cast Away Stones” (edited to minimize spoilers):
Trelawny was certainly a liar who eventually came to believe his own melodramatic fabulations … but his adventures on Mount Parnassus did happen. He really was the barbaric right-hand man of the mountain warlord Odysseus Androutses, really did marry the thirteen-year-old Tersitza, [etc]. His injuries were exactly as I describe them … .
I understand that these disclaimers are boilerplate, but it bothers me when they are such transparent lies. Lawyers and publishers are supposed to have more regard for the truth than this. If I had my way, a publisher that regularly inserted such disclaimers where they were so clearly false would be barred from relying on them in closer cases. Those who are careless with words are careless with their credibility.
