ROME: View from the Janiculum

I've devised a plan. The Janiculum (Gianicolo) offers the best view of Rome's cityscape, its layered skylines of domes and monuments. Instead of wandering to the Seven Hills of Rome and making drawings, I will draw at several points along this ridge, across the Tiber from the city.  

These rough sketches will serve as underlay and components for creating an expansive View drawing which combines all drawings from different view points.
