Centres, or centre-pieces of wood, are put by builders under an arch of stone while it is in the process of construction till the keystone is put in.

The pleasures are sent for firewood, and the hell begins in this life.
When, however, you have an enemy, then do not requite him good for evil: for that would shame him. Instead, prove that he did some good for you. And rather be angry than put to shame! And when you are cursed, I do not like it that you want to bless. Rather curse a little also! And if you are done a great injustice, then quickly add five small ones. Hideous to behold is he who is obsessed with an injustice.
