Mysterious Kap Dwa: Is the two-headed Patagonian giant true story or fiction?

Countless people have claimed to encounter giants throughout history. Greek titans, various Norse giants, the Chinese giant Pangu, and the Biblical giants Goliath and Anak are all examples of stories of extremely large beings in different cultures. This has led many to wonder if real giants ever existed. One example which has been suggested as a possibility is the giant Kap Dwa. Kap Dwa is alleged to be a Patagonian giant discovered off the coast of South America. The body is unusual not just in its gigantic stature, but also in the fact that it has two heads. Could this giant be real? It is scientifically plausible, but its association with P. T. Barnum and the fact that it has not been examined by experts call this giant’s authenticity into question.

Kap Dwa is said to be a 12-foot (3.66 meter) tall giant, the body of which is in a museum in Baltimore, Maryland, USA. It is said to be a Patagonian giant. Patagonia was considered a land inhabited by giants for a long time. The legend of Patagonian giants goes back to a story told by the explorer Ferdinand Magellan.

Magellan and his men stopped on the beaches of South America and went inland to explore. As they explored, it is said they encountered natives that were twice the size of a normal man. This is probably because a few of the indigenous peoples of the region, namely the Tehuelche, do happen to be taller than the average European was at the time. This height difference may have been exaggerated, leading to the long-standing European myth that Patagonia was a land of giants.

Is it possible though that there may have been a few real giants in Patagonia and that Kap Dwa is an example of them?

The Histories (or Legends)

There are two conflicting stories of the origin of Kap Dwa. According to the first, Kap Dwa was encountered by Spanish sailors in around 1673 on the beaches of Patagonia. He was captured and taken onto their ship where they strapped him to the mast. When he got free of the mast, he skirmished with them and was killed by a pike piercing his chest. After this his body was mummified and stuffed and eventually made its way first to Britain and later the United States in the 19th century; where it became the subject of many sideshows and freak shows as a spectacle of the unexplored world.

The second story is that the giant was found already dead on a beach with a spear through his chest. In this version, his body was found by Paraguay natives who mummified the body and worshiped it in a sort of religious ceremony. At some point after this, the British schooner captain George Bickle heard about it. He infiltrated Paraguay and stole the body. After having taken the body, he brought it with him to Britain.

Both stories end the same way: The body ends up in the hands of showmen who add it to their collection of curiosities.

There is some disagreement over its authenticity. Some believe it to be genuine and others are convinced it is a hoax. Let us examine the evidence and see which one sounds more likely.

Is a Two-Headed 12 Foot Man Even Possible?

Although a real two-headed giant seems pretty far-fetched, on par with discovering a real dragon or a real troll, it is not actually as unlikely as it sounds. Let us first examine the creature’s unusual height. There have been people of unusual stature due to the condition known as gigantism. The tallest person in recorded history for which there is indisputable evidence is Robert Wadlow (1918-1940) who was 8 feet 11 inches (2.47 meters) tall and still growing when he suddenly died at the age of 22.

Although people have been found who are over 8 feet tall, no living people or skeletal remains (for which the evidence is beyond dispute) have been found that are 12 feet tall. Although it may be possible for a human to grow to that size, increasing health complications make it more difficult for someone to reach that height and survive. The reason that Wadlow died is because his feet developed blisters because of the enormous weight on them. These blisters eventually became infected and he died from complications related to the infection. These health problems would only get worse for someone who was 12 feet tall.

People and animals with multiple heads have also been identified. One of the ways that conjoined twins can form is a condition called dicephalic parapagus, in which the twins will appear to have one body and two heads. Again, most cases do not survive infancy let alone to adulthood, but there are a few rare cases that do. The two most famous examples would be the Italian brothers Giovanni and Giacomo Battista Tocci (1875/1877-1940?) and the American sisters from Minnesota named Abby and Brittany Hensel (1990- present). The chances of survival for dicephalic parapagus twins is increased if their vital organs are doubled so that each twin has a separate heart, stomach, set of lungs, etc. It is thus possible for dicephalic parapagus twins to become biologically successful adults, but it is very rare.

Medical Knowledge vs the Legend

For Kap Dwa to be genuine, we would have to suppose two very unlikely scenarios at once. We would have to presume that dicephalic parapagus twins were born who had yet another rare and lifespan-reducing disorder, gigantism, and they were somehow able to overcome all the health problems related to both conditions and become full-fledged adults that were strong and healthy enough to engage in combat with a band of sailors. While this is not out of the question, it does make the story much more unlikely and in need of considerably more evidence.

The body was allegedly examined by physicians in the 1960s who said that it showed no obvious signs of being fake. No other experts appear to have examined the body either to determine if it is genuine or if it had the internal anatomic requirements to be likely to survive as a set of dicephalic parapagus twins.
