What did Nostradamus invent?

Nostradamus did not invent anything in the modern sense of the word. He was a 16th-century French astrologer, physician, and alchemist known for his book of prophecies, *Les Prophéties*.

Here's why it's important to clarify:

* Nostradamus's Work: His "predictions" are written in cryptic quatrains (four-line poems) that can be interpreted in various ways. They are not scientific or technological inventions.

* Historical Context: During his time, astrology, alchemy, and other mystical practices were widely accepted and practiced. Nostradamus was part of this intellectual climate.

* Modern Perception: Nostradamus is often associated with prophecies and predicting the future, although his work is open to interpretation and debated by historians and scholars.

So, while he may be famous for his "predictions," Nostradamus didn't invent anything in the way we understand the term today.
