To India! We go together with one of the most original minds of the late antique and early medieval world: Cosmas Indicopleustes. Cosmas thought that the world was a box. He thought that god resided in its lid. But he also travelled a large part of that box! 1/ #medievaltwitter

Cosmas was born at the end of the fifth or the beginning of the sixth century probably in Alexandria, the great city of Roman Egypt. We actually don’t know his real name, Cosmas the India-Sailor is a monicker he got around 9th century. 2/

We know though that he became a merchant in Constantinople. From there he traveled south to Egypt and then to the kingdom of Aksum, modern day Ethiopia. He is best informed about the topography of the region and there is little doubt that he visited it in person. 3/

He is called the India-Sailor because of his description of the current-day Malabar coast and Sri Lanka. But has he made it that far? Was it even viable in the sixth century? 4/

Cosmas does mention detailed descriptions of the South Asian fauna and flora like the hog-deer which he has “seen and eaten”. He also knows coconuts and pepper and seems to have understood if not witnessed how they were harvested. 5/
