Why Voynichese doesn't have cribs?

[Jorge_Stolfi]

Even if someone assumes that this labels the handful of stars here, it not necessarily means "Pleiades"; it could also mean "seven", "the seven sisters", "the bright ones" or anything else.

Defintely!

As long as we have no idea about the source language or accent and it's specific naming for this "obvious" star constellation, that cannot work as a crib.

I understood Rafal as saying that a crib is a word which we suspect to be the code for a certain word.  If we must know for sure, then, indeed, that doary is not a crib...

All the best, --stolfi
