One of the main themes is the idea of the 'civilized' world versus the 'wild' world. Tarzan is caught between his upbringing in the jungle and his connection to the human society that he discovers. Another theme is love, as seen in his relationship with Jane. Also, survival is a key theme as Tarzan has to constantly fight for his life and adapt to different situations in the jungle.
Tarzan himself is the most important character. He is the main focus of the story, a man - boy raised by apes in the jungle. Then there's Jane. She is the love interest of Tarzan and represents the civilized world. Kerchak, the leader of the ape tribe that raised Tarzan, is also very important as he has a big influence on Tarzan's early life.
The Legend of Tarzan is purely fictional. It's a work of imagination that combines adventure and fantasy elements to create an entertaining story, not based on real events or people.
Tarzan is indeed an original story. It introduced unique characters and settings that captured the imagination of many. The concept and plot were crafted specifically by the author and weren't based on pre-existing works to a significant extent.
The original Tarzan story was written by Edgar Rice Burroughs. His vivid imagination and storytelling skills brought Tarzan to life and made the character popular worldwide. Burroughs' novels featuring Tarzan have had a lasting impact on adventure literature.
One main element is the idea of a human raised in the wild. Tarzan was brought up by apes, which is a central part of the real - story basis. Another is his struggle between his wild upbringing and his human heritage. He has to figure out his place in both the jungle world and the human world.
Tarzan himself is of course the most important. Then there's Jane, the woman he falls in love with. Kerchak, the ape leader, also plays a significant role as he is in a way Tarzan's adoptive father in the ape world.
