What are these scripts?

Can anyone identify the scripts on these two pictures?

A guy sent them to me more than a year ago, asking me (!) to identify the
scripts.

I looked up some books, and ventured to replay that <Stone.jpg> (a carved
stone bough "somewhere in Asia") could have been an early form of Arabic,
and that <Seal.jpg> (a metal piece of a book cover) could have been
Nestorian, or some other Asian script of Aramaic ascent...

That guy swallowed my haphazard explanations with a "thanks"... how big a
blunder did I make, actually?

Thanks.
