I bought this in the summer of 1977 and while I don’t remember buying it I do remember reading it next to Columbia Lake at the University of Waterloo. I think the lake had been closed to swimmers 1 by then but maybe we dropped by to hang out next to it on the bank.
What impressed me at the time about this book was the sweep of history, as the immortal protagonist witnesses a thousand years of history. Why it was this book that struck me that way and not, say, the Foundation series I am not sure but it could have been that Foundation changes points of view as it changes eras.
