This book aims to collect, discuss and analyse all references to boats with connections to the Iberian Peninsula, Morocco, and the Balearic and Canary Islands. They range from the earliest prehistory to the Augustan Principate. The vessels studied were built in the western Mediterranean and nearby Oceanic coasts, or reached these areas before the technological standardization that the Roman Empire brought to the whole Mediterranean. The research presents an overview of the historical sources relating to pre-Roman navigation.
