Whoever crosses a river with hands unwashed of wickedness, the gods are angry with him and bring trouble upon him afterwards. At a cheerful festival of the gods do not cut the withered from the quick upon that which has five branchesI.e.“do not cut your finger-nails.” with bright steel. Never put the ladle upon the mixing-bowlat a wine party, for malignant ill-luck is attached to that. When you are building a house, do not leave it rough hewn, or a cawing crow may settle on it and croak. Take nothing to eat or to wash with from uncharmed pots, for in them there is mischief. Do not let a boy of twelve years sit on things which may not be moved,I.e.things which it would be sacrilege to disturb, such as tombs. for that is bad, and makes a man unmanly; nor yet a child of twelve months, for that has the same effect. A man should not clean his body with water in which a woman has washed, for there is bitter mischief in that also for a time.When you come upon a burning sacrifice, do not make a mock of mysteries, for Heaven is angry at this also. Never make water in the mouths of rivers which flow to the sea, nor yet in springs; but be careful to avoid this. And do not ease yourself in them: it is not well to do this.
