Have you ever wonder why some people's greatness is recognized after a monumental body of work some others achieve the same status with just one master piece?
Two examples come to my mind and either and each person is regarded as a genius, no doubt about it. Because they are.
And in both couples, the protagonists are contemporary of one another.
My first example are Michelangelo and Leonardo. Buonarroti made many titanic works, feats of strength and mastery, like the 5 mts. David or the Sistine Chapel. Beauty and skill. Impossible feats. Will and power. A true Master. His works are so vast and there are so many of them, one can't encompass any of them at a glance. You can only appreciate them from a certain distance. Things only a giant woud achieve.
Da Vinci, on the contrary, is famous for a few masterpieces, like Mona Lisa or the Last Supper, and was deemed in his time as untrustworthy because he didn't finished some of them. Did that prevent him to be regarded at the same level as Michelangelo? Nope. You may like one more than the other, but their status as Geniuses is practicaly the same. No doubt about it.
My other example are The Bard and the One Handed Man from Lepanto. It is impossible to name all the works from Shakespeare from the top of your head. There are so many. Some believe it's not possible they all came from just one man. Immortal scenes and phrases, cultural icons. The greatest English writer. One of the greatest of all time.
To refer to Cervantes, you just have to name the Quixote, l & ll. The top of Spanish Literature, the greatest Spanish Author. Phrases and cites impervious to the passing of time. A story for the ages. How did one opus achieved the same status of Shakespeare's vast body of work? A mystery.
I don't know how to define or even name this phenomenon, it just came to my attention. Why a few compare to so many? It puzzles me.
Same as Spain is regarded as discovering a new part of the Word for one journey, and England has to plant their seed in countless countries to be considered both Nations as conquerors.
Perhaps it comes from religion: the gods are extremely worried for this miserable rock we are living on, disregarding the vastness of the universe, but, undeniably, they both coexist with each other and both are indispensable to our life.
