Other forms: plinths
A plinth is the block a column or a statue stands on. It lifts the thing above eye level and says it matters.
Architecture uses it precisely for the lowest square part of a column base, and galleries use it for the box a sculpture sits on, where the choice of height and colour is a real curatorial decision. Trafalgar Square has a famous empty one, used for a rotating series of commissioned works. Pedestal is the near synonym, and putting somebody on a pedestal is the figurative version.
