I've had this book for a while now and always wondered who it originally belonged to, if that could be determined. Its an epitome of Roman history, printed in Amsterdam in 1625, and the binding appears in every way contemporary with that. I included pictures of the other ownership marks inside. Some might be helpful or interesting. If anybody by chance recognizes this crest, or could point me towards a good resource I'd be very appreciative. I included the link in the first comment, thanks everybody!

P.S. - If this is the wrong subreddit for this I apologize.
