Nostradamus C3 Q13: Furnace used to clean German city of cholera.
Copyright: Allan Webber, December 2015

The text in this verse gives a description of an electrical device used to manufacture fuel for a submersible machine. The same tone can be found in the anagrams but it redirects the focus to a generator (or et argen) used for destroying infectious waste during a bout of cholera (l'arche or) in a citadel (De la cit). However when a German (manger) made pellet (te le pl) is found (fondu) it releases a foul (foul)  reagent (et argen).

The anagrams setting the frame for understanding this Prophecy include:

1. Foul lender learned greater  generator reach far pound often cholera reagent found
2. Argumental era exuded if neutral german lifts Vultan pact
3. Pellus elucidated pellets dangers grandest citadel tuned 
4. Submerged aquan scales eagle genera range

C3 Q13
Original Verse in English and French (Benoit Ed.)

Through lightning in the arch gold and silver melt
Of two captives one will eat the other:
The greatest one of the city stretched out,
When submerged the fleet will swim.

Par fouldre en l'arche or et argent fondu
De deux captifs l'vn lautre mangera
De la cite le plus grand eſtendu
Quand ſubmergee la claſſe nagera.
