Antique memento mori in bone, finely carved, mounted on a small wooden base.
"The phrase "Memento Mori" originates from a particular custom typical of ancient Rome: when a general returned to the city after a war triumph and parading in the streets, he collected the honors that were bestowed on him by the crowd, he ran the risk of being overwhelmed by pride and delusions of grandeur. To prevent this from happening someone, behind him, pronounced the phrase: «Respice post te. Hominem te memento »("Look behind you. Remember you are a man")"
