You've heard of the story about the Achilles Heel or a Glass Jaw. Today, Mark Bertrang shares the story about The Glass Bull. Decades ago, Mark purchased this bull in the village of Murano on an outlying island of Venice, Italy. A small group of world class glass factories are located there, where handblown works of art are produced. Mark carried this bull throughout Italy fearful it would break. It didn't. Yet as it was then, it is still a fragile piece that helps to tell a story of beauty and venerability today.
