The two pictures are "Venus de Milo" and "The Mouth of Truth" which appeared in the movie Roman Holiday. Why Venus has no arms and hands is a question people ask over and over again. Also focusing on "hand," legend says that if you are a liar and put your hand inside The Mouth of Truth, you will lose fingers.

I connected the relevance between pictures and made up a new story: Venus must have lied, and in order not to be verified by The Mouth of Truth, she just simply cut off her arms to avoid the examination.
