Sailing and sailing rigs in the Ancient Mediterranean: Implications of continuity, variation and change in propulsion technology

Ships and boats form the foundations of the maritime connectivity that is a central part of our understanding of the ancient Mediterranean. While the general chronological sequence of sail and sailing-rig development is well established, the implications are less-well discussed. This article sets out how sails and sailing rigs developed in antiquity, with emphasis on the Greco-Roman world. Subsequently, instances of innovation are defined. Why specific pieces of maritime technology were, or were not, widely adopted is considered. Long-term technological continuity can be comprehended, and a shared maritime culture of sailing in the ancient Mediterranean is suggested
