When did barometer become figurative?

Originally, barometer referred to an instrument that measures atmospheric pressure. Although this meaning is still very much in use, the word has taken on a strongly figurative sense denoting something that signals changes in conditions not necessarily related to the weather. This extended use of barometer has existed since at least the early 18th century, when Isaac Bickerstaff used it in an article in The Tatler: “I have an Engine in my Study, which is a Sort of a Political Barometer, or, to speak more intelligibly, a State Weather-Glass.”
