The Queen of the Night by Dominique Collon spends a little time talking about where and when the plaque was found and its history with the museum. Most of the little book (they’re only about 40 pages) discusses what the plaque might represent. Given the location of the find the Queen of the Night is likely to be a goddess and there is some debate whether she is Lillith, Ishtar or Ereshkigal. The symbolism seems to point to the latter, but there’s actually no way we ever know what the plaque really depicted or what it was for.
The plaque has microscopic traces of paint on it and so a reconstruction of what it would have originally have looked like has been created. Which is very cool. I imagine it would be quite striking in a dark temple lit only by candles.
