I'm not sure if there are a large number of specifically named 'ptlomey astronomy historical fiction' works. However, some general historical fiction books about astronomy might touch on Ptolemy's ideas. For instance, in some books that explore the history of astronomy, they might include sections on how Ptolemy's model of the universe influenced scientific thinking at the time. This gives a fictionalized view of the era when his ideas were dominant.
There might be some self - published or relatively unknown works in the realm of 'ptlomey astronomy historical fiction'. It could be that in some local libraries or small - scale literary collections, there are stories that are set in the time when Ptolemy's astronomy was the main view. These might not be widely known but could be real gems for those interested in this very specific genre. You could try reaching out to astronomy enthusiasts or local historical fiction groups to see if they know of any such works.
One example could be 'The Planets' which often delves into Ptolemaic astronomy concepts within a historical context. It weaves together fictional stories around the understanding of the planets as per Ptolemy's ideas.
