A two-wheeled variant, the “oxcart” (Italian baroccio), is found in the canting arms of di Barozi, mid-15th C. [Triv 76].Society variants of the wagon include the “covered wagon”, with a cloth covering stretched over circular hoops; the illustration is taken from the Douce psalter, c.1320. Similar is the “pageant wagon”, a wheeled performance stage, with curtains and ornamentation, used in 15th Century England. Finally, there’s the “war-wagon”, with an embattled top and arrow slits. None of these variants have yet been attested in period armory; moreover, the pageant wagon carries a step from period practice. For related charges, see wheelbarrow.
