Nostradamus C2Q100: Great floods create autocratic island states where adultery is punishable by death.
Copyright: Allan Webber, December 2015

In this verse Tiletanus (aka Josse Raveysteyn), see Josse_Ravesteyn in Wikipedia) ,a 16thC Catholic writer on the significance of the scriptures, is used as an example of those who use religion to stand in judgement of those who they deem sinful.

These foundations can be seen arising out of the third lines taxt and anagrams.

Firstly there is a message that all letters in that line to create  a continuous series of anagrams. Its message is Tletanus grandstander predates rules (_insulte Ta_nt grand $era d_es predat_eurs l')

It also has grandest spared adulterers sin adulterers spared  (_t grand $e_ra des p_redateurs l_ins_)   and departures treasures dangers spread(

This is strengthened  by the variant forms of similar anagrams in the first line
