Magdaleno Fierro handcrafts this ceramic tree of life to celebrate the world of nature. Yellow and red butterflies flock to the terracotta tree that is covered with red leaves and yellow-orange flowers. A bouquet of four calla lilies is nestled where the limbs begin to branch out from the trunk. <br><br>The tree of life is a quintessentially Mexican expression of folk art, often a biblical allegory told in clay.
