Franz Ritter (15?? - 1641), also known as 'Franciscum' was a German mathematician, cartographer and astronomer active in Nuremberg during the last half of the 17th century. In cartographic circles Ritter was admired for his introduction of an unusual geonomic projectionwhere he applied his knowledge of astrolabes and sundials to the art of cartography. Ritter did not take any apprenices and consequently many of his cartographic innovations were forgotten after his death.

This item has been carefully restored and recreated onto a heavy 100% cotton canvas and not a fragile paper. My items can be easily rolled to be presented as a gift or retrieved from storage to be unrolled to reveal a fascinating historical conversation piece. Search your family history and geneology.

The map appearance I am trying to achieve is that of a map that has been bound in an atlas that has been lovingly cared for over the last 100+ years, with the original hand coloring. On certain monitors and smart phones, colors may look excessively bright because your screen is lit from behind. I can assure you that the colors will not be so garish when you receive your map. Instead you will be appreciative of the heft and quality of the highly textured canvas, which can sustain a certain amount of rolling up and abuse. These were designed to be heirlooms.

Your map has a protective coating which allows it to be handled with reasonable care and to be framed WITHOUT heavy, breakable, glaring glass. Feel free to run your hands along the nicely textured surface.


Your item will come with unfinished edges. This provides extra protection in shipping and versatility in the presentation.

You will need to trim your canvas with sharp scissors to get the aesthetic look you desire. For pinning to your wall, the cutting line is obvious although some people leave additional margin at the bottom to accommodate the title.

If you intend to frame your item, you should not crop your map any further, but leave the excess margin for the framer to deal with.

You can also frame it yourself! Not all that hard to do. A rustic looking frame will enhance its appearance or just use the 4 map pins, provided at no charge, to tack to your wall or message board. There's also a little piece of decorative string to tie your map if you are gifting it!
