Natalina "Lina" Cavalieri was an Italian operatic dramatic soprano, actress, and monologist.

A monologist, or interchangeably monologuist, is a solo artist who recites or gives dramatic readings from a monologue, soliloquy, poetry, or work of literature, for the entertainment of an audience. The term can also refer to a person who monopolizes a conversation; and, in an obsolete sense, could describe a bird with an unchanging, repetitive song.
