I assess this line as offering high quality  evidence that Nostradamus writings contain astronomic code.

C I. Q47  line 4 Nostredame star images result on Valoix lines 
anagrams l-ESMAGI-STRA-TESDAMNERO-(O)N-TLEURS-LOIXVA-INES(L)
C I. Q47 line 4 Les magistrates damneront leurs loix vaines
meaning The authorities will damn their useless powers

Note that this line forms a near perfect anagram series (perfect if it uses every letter  and only required to use it once). It is consistent within itself and with Nostradamus works. It is also true that its visible words and the hidden code have no inconsistency (even though it's a none specific link). There is also truth in the code as his most famous prophecies were those easily linked to the Royal Valoix / Valois family.

The natural order of the anagram series seems to be good especially reading from right to left. (Valoix lines and Nostredame star images form clusters).

Nostradamus is the latinized form of Nostredame.

See Astronomy page for further insight into the power and accuracy held in this line.
