Code of the Week / Re: Double Columnar Transposition
« Last post by george4096 on December 02, 2013, 02:15:45 PM »
Hi Phil

I am new to the forum and also like double transpositions. A couple of questions:
1) In the same key used for both transpositions.
2) Could you give a general idea of the key lengths. Are they less than 10, or around 10, 15, 20, or more.

I have developed a program for that, but this would take too much time to test 25 x 25 = 625 possible options for key lengths. Also, when I have an idea about the approximate key length, then based on the cipher text lengths, I can evaluate if at all there are chances of success.

Also, did you take the quotes accurately word by word/letter by letter, or should we expect deviations from the "official" known quotes. I am asking because a known plain text attach would also be an option, which wont work if the text is not exactly as expected.

I can't say I know of that, nor have I heard of Farghani. Looks like he was an early astronomer that made some vital contributions.

The Voynich astronomical section (ff. 68r-69v) could be from a Jewish copy of the 12th or 13thC translation of Al Farghani.
Jus' sayin.

Would be glad to know where to find detailed  information on these.

I was hoping the table for generating words/names might spark some interest.

Wait and see, I guess.  ;)

Yeah, I know the 72 divine names are heavily used in mythology... if it is indeed an alchemy book of some kind then that kind of inclusion would make sense.

Panofsky's freely-given opinion to Ann Nill was that the Voynich manuscript was not continental European but Spanish, Kabbalistic and Mozarabic Jewish. He initially placed it to the thirteenth century, but not having access to some mss now available he could not explain the form for the 'nymphs' so early.  More recent information, including discription description of the pigments by McCrone and discovery (by the present writer) of motifs which link the Vms to the portolan-chart tradition,  make the fourteenth century and Jewish context more likely for a recension prior to ours.

So the 'ladies' in the calendar section could be named by the 72 divine/angelic names used in Kabbalah.

There's a web-page  referring to Kircher's table of 72 angelic divine names from his Oedipus Aegyptiacus.


a quotation from the Bahir - par.10 - where it says of the 72 Names: "... These are the 72 names.  They emanate and divide themselves into three sections, 24 to each section. Each sections has four directions to watch, east, west, north and south. They are therefore distributed, six to each direction. ..."

comparative table of the 72 names as rendered by Bardon, Agrippa and Abulafia

that by Francis Barrett (1801)

the system by which the names are generated in the original Hebrew

NB: - also much nonsense on the same the web-page.

Creepy. I'd say that's a typo but they repeated it multiple times...

The Star Dust left Buenos Aires at 1:46 PM on 2 August 1947, bound for Santiago. Passengers were:
1--Casis Said Atalah, a Palestinian returning home to Chile from a visit to his dying mother;
2--Jack Gooderham, businessman;
3--Harald Pagh, businessman;
4--Peter Young, an agent for Dunlop;
5--Marta Limpert, with the ashes of her deceased husband, returning home to Chile after being stranded in Germany during the war;
6--Paul Simpson, a King's Messenger.

Santiago received a routine message in Morse Code from the plane at 5:41 PM, announcing an expected arrival in 4 minutes. The complete message was
"ETA SANTIAGO 17.45 HRS STENDEC". "STENDEC" was not recognized as a word. The Chilean Air Force radio operator at the Santiago airport described this transmission as coming in "loud and clear" but very fast. He requested clarification and heard "STENDEC" repeated twice in succession before contact with the aircraft was lost.

It was not until 1998 that mountaineers found some of the remains.

Quoted and paraphrased from an on-line article. I think it was this one.

The meaning of "STENDEC" (... - . -. -.. . -.-..) has not been discovered. Perhaps one or more spaces is in the wrong place. There are several Morse Code convertors on-line. One is at the above address. Here is another.
