Outdoor large stone vertical fountains can become the symbol of the square. This vertical fountain has three layers as a whole, the cistern is polygonal, and there are many relief designs of storylines on the outer wall. Also on the upper edge lie many Roman figures holding jars that could serve as fountains. Each floor of the central cistern of the vertical fountain has figure sculptures, from the Roman man Optimus Prime at the bottom, the woman on the middle floor, to the child sculpture at the top, all of which have historical development and mythology. Ancient Roman vertical fountain sculpture was greatly influenced by Greek sculpture art. However, due to the influence of imperial rule and secular culture, different from Greek sculptures, which are mostly based on myths or sports competitions, Roman sculptures are more extensive, and pay equal attention to statues of gods and secular emperors and nobles. Only the vertical fountain has inherited more characteristics of Greek sculpture art, and its materials are mostly based on natural themes such as animals and plants, and are often created with the background of legendary myths.
