The word "scanned" used 2600 years ago

"Let sleep not come upon thy languid eyes Before each daily action thou hast scann'd; What's done amiss, what done, what left undone; From first to last examine all, and then Blame what is wrong in what is right rejoice."

This was either a poem or a short saying of Pythogoras. It can be found in the Discourses of Epictetus, Chapter 10, Book 3.
