Res Mancipi

Res Mancipi. The Res Mancipi of old Roman law were, land-in historical times, land on Italian soil-slaves, and beasts of burden, such as horses and oxen; and the mode of conveyance by which they were transferred was called a Mancipium or Mancipation. Distinguished from them was another class called Res nec Mancipi, 'things which did not require a Mancipation,' i.e., could be transferred by a simpler mode of assurance, and were held to pass by mere delivery: see Maine's Ancient Law, Ch. VIII.
