In 47 BC, Julius Caesar goes over his strategy with Cleopatra against her brother Ptolemy XIII. The battle being prepared for is the Battle of the Nile, which will decisively put Cleopatra on the throne as Queen of Egypt in Ptolemy's place.
This was actually an assignment for my Concept Sketching class. We had to practice with sketching an environment in one-point perspective and then "embellishing" it using markers, ink, and special marker paper. I chose my kitchen for the environment in question (the table Caesar has laid his map on is actually the kitchen's island counter).
