I should perhaps point out that when I showed this page to David Juste, he 
suggested that this page might contain the means for translating between 
two systems of houses - not every system in use was based on a division 
into twelve.

Also: f67v2 looks as though it might be some kind of wind-rose. As well as 
Leonardo da Vinci's wind-rose which I posted recently, here is another set 
that Filarete lists [with Spencer's notes on what Filarete was copying from 
in brackets]:-

	South:	Austro, Africo, Notte [Leuconotus]
	East:	Euro, Subsolano, Vulturno,
	West:	Zephiro, Circio [Euricicias], Favonio
	North:	Boreas, Aquilone, Eurus

John Spencer also lists (in a later footnote) a comparison between the 
wind-roses of Filarete, Vitruvius, and Francesco di Giorgio. Note: the 
absence of a North wind list is (I assume) deliberate:-

	Filarete		Vitruvius	Francesco di Giorgio
NW	Corus		Caurus		Maestro, Argestes, Careus
NE	Boreas		Aquilo		Greco, Boreas, Aquilo
E	Subsolanus	Solanus	Levante[,] Apheliote, Subsolano
SE	Euro		Eurus		Sirocho, Eurus, Vuturnus
S	Nottus		Auster		Astro, Notus, Auster
SW	Africus		Africus		Garbino, Libs, Aphiricus [sic]
W	Zephirus/Circinus  Favonius	Ponente, Zephyrus, Favonius

From the text, it seems that Romagnan folk-knowledge resolves the North 
wind into NE and NW winds. Perhaps, then a set of crypto cribs for f67v2 
arising from this might look like:-

	NW	Corus			soaiin
	NE	Boreas			dalam
	SW	Africus/Auster		sary
	SE	Auster/Euro		okoral

Make of this what you will. :-)
