Nostradamus C4 Q11: Ancient meter models determine the major ciphers.
Copyright: Allan Webber, December 2015

The events in this verse's text tie into themes in nearby verses which builds a story of a waterlogged quay in an oil port located on a river delta. The last line has a peculiar tone that is resolved by the emphasis on truer meter  and true verse within its anagrams. The line says Under murder murder will be perpetrated and this makes sense when a particular style of meter becomes the cipher for murder. In this instance it is the repeated sound of tr-rt that is the murder cipher while in the other lines ql-lq /cl-lc becomes the cipher for floods or excess liquids and ou the meter of liquid fuel.

There is a small group of anagrams that enrich this verse's tale and these include: 

Apep clue quay war Argo wrote regulated graal and capped Yule
Celuy qu'aura gouuert de la grand cappe

Eridanus (constellation) induct equal claques acquit space arrest
Sera induict a quelque cas patrer

develops grievous rogues driven on fount iller
Les douze rouges viendront fouiller la nappe

so sub[s]ume true meter truer verse reinvested prepared Peter rouse
Soubz meurte meurtre ſe viendra perpetrer

# claques: professional applauders employed to cheer and clap.
