• Wagon bow — A regional or archaic term used to designate a curved wooden support, an elastic strap, or a tensioned structural element within the assembly of traditional wagons, used to absorb shocks or secure the canvas cover. In a technical crafting sense, arcior functions as a rudimentary suspension spring, made from an elastic wood essence (hornbeam or ash) heat-shaped to ensure vehicle flexibility.
• Arciorgano — An historical keyboard musical instrument from the organ family, designed in the 16th century by theorist Nicola Vicentino, structurally equipped with multiple keyboards and a complex system of microtonal pipes adapted to render up to 31 intervals per octave. This experimental acoustic device was used during the Renaissance to explore the chromatic and enharmonic genres of ancient Greek music and to achieve just intonation in academic polyphonic performances.
