How was property originally acquired in Roman law?

Roman property law recognized original modes of acquisition where new property rights were established over objects not subject to pre-existing ownership. Concepts like specificatio involved creating a completely new thing out of another's materials, such as making wine from grapes. Another underlying principle was accessio, where the owner of a principal property acquired ownership of an accessory merged into it. These ancient civilian concepts continue to influence modern property and international legal systems.
