In May 2006, I made a special coordinated visit to the Spanish Army museum (Museo del Ejercito) in Madrid, Spain.
The tent was fascinating, and may be the first hard evidence of a spoke design. The museum lists the tent as belonging to Carlos V, which it did, but according to Marianne Perdomo, it originally belonged to the Portuguese Admiral Martin Afonso de Sousa .
The tent is dated 1542-1545, when Admiral Sousa was governor of the Portuguese colony in India. It would have been made in muslim India but they say that similar techniques were used in 15th and 16th Iberia. Sousa's arms are on the entrance awning and Charles V would have added the eagle on top when he later received it as a present.
The furniture inside is of a later, non-specified, date.
[NOTE: the center pole is modern, and the museum staff could tell me nothing about how they thought it would have originally been set up. The tent had museum lights in it, and we were not allowed to use a flash. I was allowed to use a flashlight so some pictures are more in focus than others. ]
The tent had two walls, and interior and an exterior. The fascinating thing for me was the discovery of slits around the interior of the eave, about every 18-24 inches. Looking closely at the slits, the slits themselves weren't remarkable, but sewn on the inside of the outer wall, at the bottom of each slit was a fancy leather patch. We looked and looked for something that might hold a perimeter pole in place, but no luck. We determined that based on the location of the patch (low in the opening) and without a grommet to slide a spike through, any perimeter poles would slip off the tip of the patch and slide up in between the two walls. Based on the location and shape of the patch, it appears to me that the slit supports a spoke and the leather patch provided the solid surface for the spoke to push on, preventing the spoke from pushing directly on the fabric of the outer wall.
If anyone has a different thought about the purpose and function of the slits and leather patches, please feel free to send them to me. I would love to have a discussion about this. ( terafan AT greydragon DOT org )
