The problem of winter navigation in the medieval Black Sea

Unlike the pre-industrial practice of winter navigation in the Mediterranean Sea, which has been the subject of numerous studies, winter seafaring on the medieval Black Sea has not previously been the subject of thorough scholarly investigation, not least because the available sources are relatively few and fairly circumstantial. Being aware of the limitations of the present survey, the author attempts to gather together and reinterpret several instances dating from the period of the Byzantine and Italian domination over the Black Sea, which can shed some light on the seamen's often complicated relation with the winter season. The majority of the extant sources date from the last two centuries of the Middle Ages, an era that witnessed substantial technological developments which contributed to the amelioration of winter navigation. This study chiefly aims to highlight the unresolved issues and address the challenges that such a topic of inquiry presents.
