WI Galilean moons discovered in antiquity

The Galilean moons are actually bright enough to be visible to the unaided eye if it weren't for the glare of Jupiter.

Now presume a very clever observer invented a device to get rid of that glare.
Frex a tube with a tiny occultation disk at the end kept in place with hairs.

The relevance is that prior to 1610 all celestial objects were thought to revolve around the Earth.
All the existing cosmologies were based on this notion.
 
I suppose somebody might make a cosmology that allows for secondary satellites while still being geocentric (I think Tycho did one). Over time it becomes as orthodox as the Ptolemaic system OTL.

Alternatively, if the knowledge of the device is lost, medieval/early modern scientists would regard the satellites as myth or fraud-until the astonishing rediscovery!

They might very well end up with the same names.
