Dancing Mania(Tarantism) is belief in Italy that a tarantula bite could lead to. The victim would experience uncontrollable and frenzied dancing as a way to "sweat out" the venom and cure the illness. This belief led to the development of a popular dance known as the "tarantella," which was said to be performed by those afflicted with tarantism in order to cure themselves.

Dancing Mania, also known as Tarantism, was a phenomenon in Italy during the late medieval and early modern periods. The belief associated with Tarantism was that a person bitten by a tarantula spider would experience a condition requiring a specific form of dancing for a supposed cure.

According to the belief, the venom of the tarantula would cause symptoms such as restlessness, anxiety, and even hallucinations. The afflicted person, called a tarantato or tarantata, was thought to need a specific kind of music and dance to sweat out the venom and be healed. The dance associated with this belief became known as the "tarantella."

The tarantella was characterized by lively and frenetic movements, and it was believed that the more intense the dance, the more effective it would be in expelling the venom. Musicians often played specific tunes associated with the tarantella to accompany the dancing.

While the concept of Tarantism and the tarantella dance had cultural and folkloric significance, it is important to note that the belief in tarantula bites causing these symptoms and the need for a dance cure were not based on scientific understanding. The phenomenon is now considered a historical curiosity and an interesting aspect of cultural history in certain regions of Italy.
