In ancient times there were superstitions concerning good and bad omens. One of these was based on the principle that every color suggests to a person who is going to do some work whether he will be successful or whether he will fail; the impression he gets from that color stays with him to the extent that it has an effect upon his work. There was also a superstition that if one met a crooked person when going to one's work one would have illIi luck: not only a crooked person, but anything crooked one sees at such a time naturally impresses one's spirit with crookedness. Not everyone knows something about features, but every person is affected by features; he receives an impression from them without knowing it, for the form suggests something which he may not be able to describe, although he can feel it. It is a language without words; it conveys something, though it is not always easy for anyone to interpret it even to himself.
