About Thomas Hobbes: He was 40 years old before he looked on geometry; which happened accidentally. Being in a gentleman's library, Euclid's Elements lay open, and "twas the 47 El. libri I" [Pythagoras' Theorem]. He read the proposition "By God", sayd he, "this is impossible:" So he reads the demonstration of it, which referred him back to such a proposition; which proposition he read. That referred him back to another, which he also read. Et sic deinceps, that at last he was demonstratively convinced of that truth. This made him in love with geometry.

John AubreySir Walter, being strangely surprised and put out of his countenance at so great a table, gives his son a damned blow over the face. His son, as rude as he was, would not strike his father, but strikes over the face the gentleman that sat next to him and said, "Box about: twill come to my father anon."
