Emily Dickinson

And were You lost, I would be – 
Though My Name
Rang loudest
On the Heavenly fame – 

And were You – saved – 
And I – condemned to be
Where You were not – 
That self – were Hell to Me – 

So We must meet apart – 
You there – I – here – 
With just the Door ajar
That Oceans are – and Prayer – 
And that White Sustenance – 
Despair –

Robert Smithson, Mirror and Crushed Shells 1969

On July 9, 1969, Robert Smithson wrote the following letter to Andy Warhol about “A Mirror and Crushed Shells”:

Dear Andy,
This is to certify that A Mirror with Crushed Shells (Sanibel Island) is an original work of art. It consists of three mirrors which may be restored if broken, and one burlap bag of crushed shells collected by the artist at Sanibel Island, April, 1969. If any shells are ever lost, the owner has the right to restore the work by collecting more shells from Sanibel Island (northern part of islansd; see map of site which is part of the work). The three mirrors are held in place in a corner by the pressure of the shells only. (See photo). The work is owned by Andy Warhol.
