“We learn by going where we need to go.” - Theodore Roethke
Have you ever paused to ponder how grateful we might feel for necessity? Sometimes, as Roethke suggests, doors of understanding open because our paths appear to be blocked and we have to confront a dilemma. The path of progress is lit most clearly by persistently asking both “why” and “why not?”
Everyone who has visited Florence has seen the Basilica di Santa Maria del Fiore, more commonly known as the Duomo (Dome in Italian). The Duomo, capped by the first large dome to be built in the Renaissance, offers powerful lessons on the enduring power of faith and vision. No one knew how to build such a huge dome when construction began on the Basilica.
When design work on the Basilica started in 1294 it was intended to be the largest Roman Catholic cathedral in the world. After more than a century of work, all of the cathedral’s structure, except for the enormous hole in the ceiling, was completed.
The series of architects who had overseen the construction of the Basilica had never come up with plans for how the dome would be completed. By architectural standards of that time, a dome of such great size would collapse under its own weight. In fact, some large medieval cathedrals, such as Beauvois, had collapsed during their construction.
In 1418 a design competition was launched to select the plan and architect who would attempt to complete the Duomo. Brunelleschi’s suggestion of first building a smaller dome to support the structure of the larger dome was accepted. This and many other unknown and unorthodox methods for construction were developed. The great octagonal dome was completed in 1436. It became the prototype for St. Peter's Basilica in Rome and every other large dome built during that era. The Duomo became the most prominent symbol of the dawning of the Renaissance.
The necessity of finishing the Duomo was what fueled Brunelleschi’s creativity. The building of such a massive masonry dome posed many technical problems. A modern understanding of physical laws and the mathematical tools for calculating stresses was centuries into the future. Brunelleschi had to rely on intuition and whatever he could learn from the large scale models he built. While he looked to the architectural successes of the past, such as the Pantheon, he was forced to come up with creative solutions for the unique design and construction problems of the present. For example, to lift 37,000 tons of material, which included over 4 million bricks, he invented hoisting machines. To deal with the challenges of stresses and fresh mortar, he came up with a herringbone design for the placement of the bricks.
The next time you face the daunting wall of necessity reflect on the wonderful breakthroughs that are possible when we scale that obstacle. Pause to remember the story of those who set out to erect the world’s largest cathedral yet had no idea how they were going to cover its dome. Fuel your efforts with the faith and hope which spring from approaching necessity as a privilege rather than a burden.
How can I harness the power of necessity? What am I doing that will deprive my children or grandchildren of the opportunity to experience the privilege of necessity?
“Restlessness is discontent, and discontent is the first necessity of progress. Show me a thoroughly satisfied man and I will show you a failure.” - Thomas A. Edison
