Spanish, September 25, 1513BalvoyaAfter climbing a steep mountain in the wilderness of Panama, when he saw a vast sea in the southeast, he couldn't help being ecstatic, because he knew the weight of his glance: discovering the Pacific Ocean.So he purposely asked his expedition team to stop at the foot of the mountain and go up the mountain alone, so as to enjoyGreat Geographical DiscoveryOf course, it is worth discussing whether this is a discovery, but this is not the topic of this article.
Why did Balboa become the first westerner to see the Pacific Ocean.Before him, many Westerners had arrived in America.ColumbusI have been here four times,Other European explorers andAdventurers also came in droves, but they were only active on the east coast of the American continent.What they are striving for is to find the strait across America to Asia, which is rich in spices and gold.
As we know, the narrow channel between two lands connecting the two sea areas is the strait;The narrow land connecting two lands in the ocean isIsthmus。At that time, explorers only had the "strait" in their mind, not the "isthmus".They did not expect that when God created the land, he would sometimes spread it to his heart's content to make the land endless;Sometimes, we should cherish the earth as gold and make the land as thin as a gossamer. The place as thin as a gossamer is the isthmus.BalvoyaHe was smart. Instead of looking for the strait, he found the Isthmus of Panama with the help of the Indians.He learned from the Indians that as long as he crossed the isthmus, he could see the great Nanyang Ocean (the name he gave to the Pacific Ocean at that time) he had succeeded.
After Balboa,Map、globeThey began to mark the narrow isthmus, connecting North and South America, and people began to know that there is a land between North and South America - the isthmus of Panama.
