This is the second installment in a series on Spanish dioramas, which I started with my previous post. The diorama shown here is also from the Museo de Aeronautica y Astronautica. It depicts the first balloon used in Spain for military purposes, from the year 1889. The diorama inscription informs us that the inflatable sphere was 10.8 meters in diameter, with a volume of 682 cubic meters. This aircraft was assigned to the 4th Company of the Engineering Arm of the Telegraphers Battalion.
The balloon was accompanied by horse drawn support vehicles supplying a hydrogen generator and a 500 meter cable. The technological contrast between this aircraft, which represented cutting edge technology at the time, and the horse drawn vehicles, which were comparatively primitive, adds to the interest of the scene.
The balloon was named Maria Cristina after the reigning Queen of Spain, who had a keen interest in lighter-than-air aircraft. Accompanied by Lieutenant-Colonel Lícer López, she participated in a test flight of the balloon to an altitude of 300 meters.
Compositionally, the diorama is nicely done. The balloon itself should naturally be the focal point of the diorama, and the artist has succeeded in making it so. The eye is immediately drawn to the balloon not just because of its size and height, but also its golden colour, which sets it apart from the greens and browns of the surroundings. In addition, the balloon is the most brightly lit object in the diorama, which adds even more emphasis. It is positioned off to one side and visually balanced by the support vehicles at the other end of the scene.
What makes this diorama especially effective is the illusion that the balloon is actually floating into the air on its own. This effect is reinforced by the slack in the control cables which the men around the balloon are handling. If all the cables were taut, they would look like stiff rods supporting the balloon, and the effect would be lost. Also, the area directly underneath the balloon is dark, hiding any physical supports. The background photograph adds a further element of realism and helps sell the scene.
