Hello, I'm an expert in cultural studies and mythology. When it comes to the existence of an angel named Castiel, it's important to distinguish between religious texts and fictional works.

In Christian, Islamic, and Jewish traditions, there are numerous angels mentioned in their respective scriptures, but there is no biblical or traditional reference to an angel named Castiel. The names of angels that are widely recognized from these religious texts include Gabriel, Michael, Raphael, and Uriel, among others.

However, the name Castiel has gained popularity from its use in the American television series "Supernatural," where Castiel is portrayed as an angel character. This is a work of fiction and not based on any religious texts or historical accounts of angels.

To summarize, while there is no historical or religious basis for an angel named Castiel, the name has been popularized through its use in modern fiction.
