tree and Saint Peter's

I drew this in a matter of minutes, standing in the window of the Vatican Pinocoteca. There was a Raphael near by, but sometimes real life outweighs the greatest masterpieces.

You can see the arch and stairway reading to the garden pavilion begun by Pope Paul IV in 1558, now known as the Casina Pio IV after the later pope who competed it. In the distance, the huge dome of Saint Peter's, and between them a beautiful pine tree that deserves a name of its own - to judge by its size, it may be as old as the buildings.
