Circles and right lines limit and close all bodies, and the mortal right-lined circle must conclude and shut up all. There is no antidote against the opium of time, which temporally considereth all things: our fathers find their graves in our short memories, and sadly tell us how we may be buried in our survivors. Gravestones tell truth scarce forty years. Generations pass while some trees stand, and old families last not three oaks.
