Rorschach test

What have we here?
A Rorschach test?
So tell me -- what is it you see?
A lacy dress from the Roaring 20's?
Or could it be a shroud,
burial garment for a long-dead queen?
A religious icon?
Does your imagination fly,
or are you simply practical:
"What we see here
are the mottled results
of decades of exposure,
a simple accident, a stain
upon a fortress someone built
when feeling threatened... "
How does what you think you know
color what you see and hear?
