Who was the first women to publish a book?

It's difficult to definitively say who the first woman to publish a book was, as early literary history is often incomplete and difficult to verify. However, some strong contenders for this title include:

* Enheduanna (circa 2300 BCE): A Mesopotamian priestess and poet, she is considered the earliest known author by name whose works have survived. Some scholars believe she wrote and published hymns and other religious texts. However, there's debate about whether these were technically "books" in the modern sense.

* Sappho (circa 630-570 BCE): A Greek poet known for her passionate love poems, Sappho's works were widely circulated and admired in ancient Greece. However, few of her poems have survived to the present day.

* Christine de Pizan (1364-1430): This Italian-born French writer was a prolific author of books on diverse subjects, including poetry, history, and political philosophy. Her work "The Book of the City of Ladies" is considered a feminist classic.

While these are some notable examples, it's crucial to remember that many women throughout history wrote and likely published works, but their contributions haven't been fully documented or recognized.
