I don't see why not.  There is an electromagnetic interaction, unmediated
by hardware, between you and the marble, which manifests as a
visual perception of it.

You cannot access resources themselves.  You can only access particular
representations of those resources, chosen by content negotiation
(perhaps trivial negotiation of the form "server proposes just one
representation, client accepts willy-nilly").

The connection between an information resource and its representation(s)
is fairly close and straightforward.  The representation you get of
Italy when you do a GET on an URL for Italy will have a rather more
abstract connection to Italy.
