English: Flag attributed to the King of "Colombo" (Kollam) in Southern India, in the Catalan Atlas of 1375. The flag shows a dove (Columbus), a pun with kingdom's name; and a Syriac Christian cross, representing the fact that Southern India already had a significant Syriac Christian presence back in the 14th century.
In the map, the flag is shown as being flown in the cities of Bixder and Elly (Ezhimala).
