Cent ans bannière, cent ans civière. The ups and downs of life. A grand seigneur who has had his banner carried before him for a century, may come to drive his hand-barrow through the streets as a costermonger.
Il faut la croix et la bannière pour l'avoir. If you want to have him, you must make a great fuss over him—you must go to meet him with cross and banner, “aller au devant de lui avec un croix et la bannière.”
