But the news was heard by Columbus, who sneered at the authorities, because he had sailed to the golden fortress in Ghana, which he thought was south of the equator, and all the experts were wrong (in fact, the experts were right, and Ghana was north of the equator).
Columbus believed the prophet Estra's statement that only one-sixth of the earth's surface is ocean, and he confused Arabic words with Romarie in his literature. Based on this, Colombia calculated that Japan was located at 85 west longitude (actually east longitude140), which shortened the distance from Japan to Saint Vincent, Cape Verde by 8,000 miles.
Columbus thought it was only necessary to sail 3080 nautical miles 68 degrees west from the Canary Islands. In fact, the distance from Tenerife (an island in the Canary Islands) to Jakarta is 73 13 nautical miles.
