Various aspects of impact that weather phenomena and climatic conditions could have upon travel, travellers and communications by land, either in short-term or in long-term context, during the Byzantine period are discussed: Were there any long-term impacts of climatic change upon communications overland? Which weather phenomena are described by the Byzantine authors as affecting people on move? What was the impact of weather upon land transport and communications? Which was the concept of weather that people on the move had and how can we combine weather reports with traveller's emotional and factual reality while experiencing meteorologically induced dangers during overland travel?

This academic professor has provided us in his Diarium (Diary) with a systematic collection of daily records of various personal, historic and literary notes. But he was also interested in recording the day-today weather, extreme weather events and other environmental phenomena, such as phenological events, vine-harvest dates etc. Over 3,000 descriptive daily records of weather and other environmental phenomena have been derived from the Diarium. Assessment of the data is

Meanwhile the surface of the sea between the European and the Asiatic coast of Bosphorus froze and converted to a passable dry land. In March an exceptional period of drought allegedly followed causing the drying up of springs and rivers. This climatological phenomenon is documented by two important chronographers, who pretend to be eyewitnesses and it is described by a number of posterior Byzantine sources. The same winter is further described as very severe by about thirty Latin Annals and Chronicles. In this paper we try to demonstrate the historical and philological efforts needed to verify the trustworthiness of the sources and the reliability of their evidence.

Although in the Balkans and Anatolia such favourable climate conditions were prevalent during the eleventh century, parts of the imperial territories were facing significant challenges as a result of external political/military pressure. The apogee of medieval Byzantine socioeconomic development, around AD 1150, coincides with a period of adverse climatic conditions for its economy, so it becomes obvious that the winter dryness and high climate variability at this time did not hinder Byzantine society and economy from achieving that level of expansion. Soon after this peak, towards the end of the twelfth century, the populations of the Byzantine world were experiencing unusual climatic conditions with marked dryness and cooler phases. The weakened Byzantine socio-political system must have contributed to the events leading to the fall of Constantinople in AD 1204 and the sack of the city. The final collapse of the Byzantine political control over western Anatolia took place half century later, thus contemporaneous with the strong cooling effect after a tropical volcanic eruption in AD 1257. We suggest that, regardless of a range of other influential factors, climate change was also an important contributing factor to the socioeconomic changes that took place in Byzantium during the Medieval Climate Anomaly. Crucially, therefore, while the relatively sophisticated and complex Byzantine society was certainly influenced by climatic conditions, and while it nevertheless displayed a significant degree of resilience, external pressures as well as tensions within the Byzantine society more broadly contributed to an increasing vulnerability in respect of climate impacts. Our interdisciplinary analysis is based on all available sources of information on the climate and society of Byzantium, that is textual (documentary), archaeological, environmental, climate and climate model-based evidence about the nature and extent of climate variability in the eastern Mediterranean. The key challenge was, therefore, to assess the relative influence to be ascribed to climate variability and change on the one hand, and on the other to the anthropogenic factors in the evolution of Byzantine state and society (such as invasions, changes in international or regional market demand and patterns of production and consumption, etc.). The focus of this interdisciplinary
