 Called the "L’albero della vita" ("The Tree of Life"; "The Golden Tree" or "The Tree of Lucignano") the central stem is supported on a Gothic reliquary, from which spread out twelve branches, surmounted by a Crucifix and a pelican.On the branches there are sprigs of coral, representing the blood of Christ.The tree is gilded and bejeweled and is signed by two jewellers, Ugolino da Vieri in 1350 and Gabriello D'Antonio in 1471.
