What is the most orthodox musical instrument in western tradition?

After inquiring and reading Utopia, the history of stringed instruments is earlier than other instruments. Because it represents the Greek native musical instrument, it is associated with the prominent Apollo and is regarded as the most orthodox musical instrument in the western tradition.

Strings are produced by rubbing or plucking the bow to vibrate the strings. Early stringed instruments were plucked instruments, such as Egyptian harp, Greek guzheng and Indian guqin. After a long evolution, the commonly used stringed instruments are violin, viola, cello, viola, harp and so on.
