Plumb and Level

A free-thinking seventeenth-century Frenchman by the name of Monsieur Thévenot published a book, in 1696, entitled L’art de Nager [1], the English translation, The Art of Swimming, being published in 1699.

To Tread Water

When not being harried by unknown assailants and cast into the water, Monsieur Thévenot found the time to invent the bubble level, circa 1660.

    I wonder how many times he was “cast into the water bound hand and foot”? Could it be because he wandered around without clothes?
