early modern stoneware from germany, particularly the rhineland, "enjoys the greatest archaeological distribution around the globe", and this includes the bartmann jugs. they have been located in archeological sites all over the world, as a sign of european colonization, emigration and trade. a pair of bartmann jugs have been documented at the site of the wreck of the english ship "sea venture", lost in 1609 off bermuda. the jugs have been dated to around 1580-90, meaning that they had survived for about two decades, including ship transport, which indicates the extent of longevity that rhenish stoneware could have. the dutch east india company routinely used bartmann jugs to transport mercury, evidence of which has been found at shipwreck sites in the north sea and as far away as western australia. frechen bartmann bottles dating from the mid 17th century have been found in graves of native inhabitants in colonial north america, near the warren river in rhode island and in camden, virginia. among the finds of period shipwrecks, bartmann jugs frequently appear among the finds. a bartmann bottle donated to the victoria and albert museum in london was most likely a bottle salvaged from the wreck of the mid-16th century warship "mary rose" in 1840.

the power rule for integrals was first demonstrated in a geometric form by italian mathematician bonaventura cavalieri in the early 17th century for all positive integer values of formula_72, and during the mid 17th century for all rational powers by the mathematicians pierre de fermat, evangelista torricelli, gilles de roberval, john wallis, and blaise pascal, each working independently. at the time, they were treatises on determining the area between the graph of a rational power function and the horizontal axis. with hindsight, however, it is considered the first general theorem of calculus to be discovered. the power rule for differentiation was derived by isaac newton and gottfried wilhelm leibniz, each independently, for rational power functions in the mid 17th century, who both then used it to derive the power rule for integrals as the inverse operation. this mirrors the conventional way the related theorems are presented in modern basic calculus textbooks, where differentiation rules usually precede integration rules.
