"The penis corresponds to one's parents, on the one hand, because it is itself the cause of children. It signifies the wife or mistress, since it is made for sexual intercourse. It indicates brothers and all blood relatives, since the interrelationship of the entire house depends upon the penis. It is a symbol of strength and physical vigor, because it is itself the cause of those qualities. That is why some people call the penis 'one's manhood.' It corresponds to speech and education because the penis is very fertile...the penis is also a sign of wealth and possessions because it alternately expands and contracts and because it is able to produce and to eliminate....It indicates poverty, servitude, and bonds, because it is also called 'constraining' and is a symbol of necessity. It also indicates the respect that is inspired by high rank: for it is called 'reverence' and respect....If the penis is doubled, it signifies that everything will be doubled, with the exception of a wife or a mistress; these will be lost. For it is impossible to use two penises at the same time. I know of a slave who dreamt that he had three penises. He was set free and, in place of one name, he had three, since he received in addition the two names of the master who had freed him. But this happened only once. One must not base one's interpretation on rare instances but rather on the more normal cases."
