Ramsinga
The Ramsinga is an ancient musical instrument from India. It is a natural trumpet consisting of four pipes of very thin metal which fit one within the other. It is mentioned in Emilio Salgari's works such as The Mystery of the Black Jungle, where it is associated with the thugee cult.
In Chapter 62 of Foucault's Pendulum the Ramsinga is also mentioned, being played by a devotee of a druidic sect .
