Here's why:
* Da Vinci's work is complex, not coded: While da Vinci's art and writings are rich with symbolism and hidden details, these are artistic choices and not a secret code. Scholars believe his work was filled with symbolic elements to convey meaning in a visually engaging way, reflecting the cultural and philosophical climate of his time.
* No evidence of a code: There's no historical record of Da Vinci ever mentioning or using a secret code. The concept of the *Da Vinci Code* is pure fiction, though it's cleverly crafted to appear plausible.
* Scholars have debunked the fictional code: Many art historians and Da Vinci experts have pointed out the inaccuracies and implausibilities of the fictional code in the novel. They argue that Brown's interpretation of Da Vinci's work is flawed and based on selective readings and misinterpretations.
In conclusion, while it's fun to speculate about secret codes and hidden meanings, there's no evidence to support the idea that Da Vinci had a secret code. His work is rich and layered with symbolism and meaning, but it's best understood through historical context and artistic interpretation, not through a fictional code.
