Nostradamus' Centuries 7 Quatrain 15 (C.VII Q.15)

Nostradamus' Centuries 7 Quatrain 15 The following verse's anagrams seem to be full of references to Yggdrasill, the Nordic Tree of Life and its use in coding the symbols of events via specific lettering. By contrast the text appears very mundane but when united with the anagrams a story of stoic resistance against non-orthodox forces is seen to overcome fire and inundation. It may well be Nostradamus' foretelling of a city near Milan, Italy that survives the disasters at the the end of this, the 21st,  century. Alongside is the modern flag of the Duchy of Milan, the main city of Insubria.   C.7 Q.15  Before the city of the Insubrian lands, for seven years the siege will be laid; a very great king enters it, the city is then free, away from its enemies. Deuant cite de l'In$ubre contree Sept ans $era le $iege deuant mis Le tre$grand Roy y fera $on entree Cite puis libre hors de $es ennemis.
