Saltatio and Nritta

Ballet is  a term that the English took from the French "Ballet de cour", which is pronounced without the ending  "t". Not everyone knows that the word has not latin origin and was created by one of the Italian Masters of the 15th century.  Actually the term used still in the Renaissance was a latin one. Two terms were in use "saltatio", meaning jumping and "tripudium" meaning dancing in excitement (for the Romans it was  the stamping of the feet in battles).All this reminds a lot of the Indian Classical dance terminology of "nritta" as pure dance (saltatio) and Nritya as dance drama (tripudium)...
