Sorry Seinfeld fans, I’m not talking about Cosmo Kramer. Cosmas Indicopuleustes was a far more fascinating figure though, although probably not as delightful at opening doors and making witty comments.

Cosmas was a writer, merchant, traveler, monk who is most famous for his 6th century tome Christian Topography in which he provided some of the earliest world maps on record for the Byzantine Emperor Justinian.

Before becoming a monk and a hermit, Cosmas was a very successful voyager and trader who visited Ethiopia, Eritrea, Sri Lanka, and most famously, India. Cosmas seemingly difficult last name was easy for Byzantines and Greeks – it was Indicopleustes and essentially means  “Voyager of the Indian Ocean” – which was helpful when you were trying to remember which Cosmas to invite to your Christmas party – you wouldn’t want to accidentally invite the one who explored the Aegean – Cosmas Aegeapleustes…that guy is impossible to deal with…

Of course, you might not have wanted to invite Cosmas Indicopleustes either since one of his most famous conventions was that the world was flat. It was he who introduced that idea to the early Christian Church. He spent considerable time in his book and in his life trying to prove that Ptolemy’s view that the Earth was a sphere was laughable.  He was of the much more (to him) reasonable opinion that it was flat and had a treasure chest type lid  on it.

He was not the person that ‘cosmology’ was named after, though it was one of his passions.  Mostly, it was the fact that he covered some serious ground and drew maps about it, that he is remembered for, though, like Donald Trump, his ridiculous views about some things eclipse his true accomplishments.
