Large Viking Wedge Tent
is made with 14 ounce waterproof canvas in two alternating colors. You can set them up with two poles but its better with a ridgepole and two poles as it is more wind resistant and neater looking. There are 6 alternating panels of color and the ends are striped too. They are 10ft wide and 10ft high, and about 15ft long. There are two heavy-duty grommets in the end of the roof for pole pins to stick through. The grommets are pretty much indestructible and sewn by hand. The doors are on both ends and have 2 sets of ties. This is not the lift-able sidewall style, but is more weather-tight. If you need to have a pole or board go through the canvas at the ridge, you can add a slit there for that pretty easy.

Viking wedge tents or more simply Viking tents, were often made of rectangular sail from the Viking ships as evidenced by the rigging seen on the few existent samples. They are very water-tight by design due to the steep walls, and fairly simple to set up. They can be set up with just 2 poles and 2 ropes to pull the ridge line tight, or with a ridge pole running the length of the tent. Due to the fact that carrying around a 15ft ridge pole for your tent can be cumbersome, often threaded pipe or splices are used to shorted the pieces. PVC or conduit will NOT work. I would not use less than 1 inch threaded pipe or a 2x4 of wood. Splices to the ridge pole can be made by getting two pieces of steel plate with holes on either side and bolt holes drilled through or rectangular tubing. It is a good idea to use a third upright pole if you put a splice in the middle, right under the splice.
Often, exterior supports in an X shape are used on Viking tents outside the tents on the ends. You would need to cut a short slit for a pipe or ridgepole to go through if you do this. Simply cut the minimum slit you need and whip the edges of the slit with any thread sort of making it look like a button hole. You can also do that near the bottom corners if you want to run pipes or poles along the bottom edges and have them stick through the end walls. X poles are easy to set up usually, as you can walk them up a bit at a time on both ends at once, and of course they look kinda nice if you carve up the ends with some decorative shape. Viking tents were used during a several hundred years span but gaps in the records make the exact timing uncertain. Basically they are though to have been used in the 8 century to as late as the 11th century, but some drawings exist of them being used much later.
