Originally, there were the  numbers 292.211 and 793.73, but Stella changed it soon after.

 

David Webb has explained it nicely in the comments of the challenge:

 

The first number, 793.73 let's you know we're doing a Dewey Decimal puzzle: (http://dewey.info/class/793.73/e23/about)

 

The second and third numbers go together, let's look them both up:

- 292.211 is "Gods and goddesses - Greek" (http://dewey.info/class/292.211/e23/about)

- 610 is "Medicine and health" (http://dewey.info/class/610/e23/about)

 

Who is the Greek god of Medicine? Google tells us it is "Asclepius"
