5 It is said, indeed, that there have been certain tribes who mourned at the birth of human beings, and kept festival at their deaths, and this not without reason, for they thought that those who had entered upon this ocean of life should be mourned over, but that they who had escaped from the waves and storms of this world should be accompanied by rejoicing not without good reason. And we too forget the birthdays of the departed, and commemorate with festal solemnity the day on which they died.
