What is "timarion"

The Timarion is a Byzantine pseudo- Lucianic satirical dialogue probably composed in the twelfth century (there are references to the eleventh-century Michael Psellus), though possibly later. The eponymous hero, on his way to a Christian fair at Thessalonica, is unexpectedly taken to Hades, which is ruled by pagan figures and pagan justice, and where " Galilæans" (that is, Christians) make up only one sect of many.
