Here is the article mentioned in the previous post. I’ll share it here for easier access.
“If Achashverosh Is Xerxes, Is Esther His Wife Amestris?”
This won’t spoil the article, but the end does mention that historical records from the Persian empire regarding Xerxes haven’t survived, and what Herodotus wrote about Xerxes ends in his seventh year. It was at the end of his seventh year when he married Esther. So Herodotus has no writings about Queen Esther.
Enjoy the article.
