(Latin: death, dead; die, dying)

cadaveric rigidity (s) (noun), cadaveric rigidities (pl)
1. The stiffening of the muscles that occurs several hours after someone dies: The medical examiner noted the degree of cadaveric rigidity or rigor mortis that was present as part of the estimation of the time of the victim's death.
2. The hardening of the muscular tissues of the body, from one to seven hours after death as a result of the coagulation of the myosinogen and paramyosinogen: The cadaveric rigidity disappears after one to five or six days, or when decomposition begins.

Sometimes the rigor mortis, or cadaveric rigidity in the corpse, makes it difficult to fit the body into the coffin for burial.

3. The postmortem stiffening of the voluntary and involuntary muscles of the body present a board-like situation for the entire body: The development of cadaveric rigidity may be poor or incomplete in elderly, very young, or severely debilitated individuals.
Calicem vitae dedisti mihi in mortem.
The cup of life is the cup of death.

Motto of German Emperor Henry VII of Luxembourg (1308-1313).

Caput mortuum.
Dead head; death's head or a skull.
Human skull.

This was a term, or name, alchemists gave to worthless material that remained after their experiments; such as, residuum left after chemical analysis; worthless residue in a flask after the distillation was complete; by extension, "a worthless or useless person".

De mortuis nihil nisi bonum.
Of the dead, (say) nothing but good.

Another translation: "Speak kindly of the dead." It is believed that Chilon of Sparta, one of the wise men of sixth-century B.C. Greece, is the author of this saying. Keep in mind that this would be a Latin translation of what Chilon said in Greek.

The advice to everyone is to speak well of the recently dead or, if you can not say anything good, to keep quiet.

Esto fidelis usque ad mortem. (Latin motto)
Translation: "Be faithful unto death."
