Instruments built by the Stradivarius family are popularly thought of amongst the pantheon of "greatest ever".1 But have they always been considered this way? Were they held in similarly high regard in their day and continuously up to the present? Were they just ordinary violins until some "great master" musician declared them the best, and the declaration became self-fulfilling?
What is the origin and history of the popular fame of the Stradivarius?
1 I make no claim one way or another about the actual quality of the instruments; I'm interested in the history or their popular reputation, regardless individual opinion of them.
