as they toured picturesque districts, like the Lake District, they might have in the carriage with them a large lens set in a picture frame, a "landscape glass" that would contract a wide view into a "picture" when held at arm's length. Barker made many efforts to increase the realism of his scenes. To fully immerse the audience in the scene, all borders of the canvas were concealed. Props were also strategically positioned on the platform where the audience stood and two windows were laid into the roof to allow natural light to flood the canvases. Two scenes could be exhibited in the rotunda simultaneously, however the rotunda at Leicester Square was the only one to do so. Houses with single scenes proved more popular to audiences as the fame of the panorama spread. Because the Leicester Square rotunda housed two panoramas, Barker needed a mechanism to clear the minds of the audience as they moved from one panorama to the other. To accomplish this, patrons walked down a dark corridor and up a long flight of stairs where their minds were supposed to be refreshed for viewing the new scene. Due to the immense size of the panorama, patrons were given orientation plans to help them navigate the scene. These glorified maps pinpointed key buildings, sites, or events exhibited on the canvas. To create a panorama, artists travelled to the sites and sketched the scenes multiple times. Typically a team of artists worked on one project with each team specializing in a certain aspect of the painting such as landscapes, people or skies. After completing their sketches, the artists typically consulted other paintings, of average size, to add further detail. Martin Meisel described the panorama: "In its impact, the Panorama was a comprehensive form, the representation not of the segment of a world, but of a world entire seen from a focal height." Though the artists painstakingly documented every detail of a scene, by doing so they created a world complete in and of itself. The first panoramas depicted urban settings, such as cities, while later panoramas depicted nature and famous military battles. The necessity for military scenes increased in part because so many were taking place. French battles commonly found their way to rotundas thanks to the feisty leadership of Napoleon Bonaparte. Henry Aston Barker's travels to France during the Peace of Amiens led him to court, where
