This Neolithic oxcart is based on two different archaeological finds: A wheel from the settlement "Federsee Alleshausen", carbon dated to 3020 - 2700 BC, and part of a wooden frame from "Reute" from around 3700 BC. Since it's highly improbable that a complete vehicle from that period will ever be found this may be the closest we can get.
The loom is more loosely based on the technology of the period.
Both objects were created for my Federsee Alleshausen scene:
