Fun with Baconian Ciphers
Part 3
Now we begin
with a review of the basics of acrostics. The following extracts are from
Wikipedia:
An acrostic is
a poem or
other form of writing in which the first letter, syllable or word of each line,
paragraph or
other recurring feature in the text spells out a word or a message. Acrostics
are common in medieval literature, where they most commonly serve to highlight
the name of the poet or his patron, or to make a prayer to a saint. They are
most common in verse works but can also appear in prose. Often the ease of
detectability of an acrostic can depend on the intention of its creator. In
some cases an author may desire an acrostic to have a better chance of being
perceived by an observant reader. Acrostics may also be used as a form of steganography
[the art and science of writing hidden messages in such a way that no one,
apart from the sender and intended recipient, suspects the existence of the
message, a form of security through obscurity], where
the author seeks to conceal the message rather than proclaim it. This might
be achieved by making the key letters uniform in appearance with the
surrounding text, or by aligning the words in such a way that the relationship
between the key letters is less obvious. This is referred to as null ciphers in steganography,
using the first letter of each word to form a hidden message in an otherwise
innocuous text. Using letters to hide a message, as in acrostic ciphers,
was popular during the Renaissance, and could employ various methods of
enciphering, such as selecting other letters than initials based on a repeating
pattern (equidistant letter sequences), or even
concealing the message by starting at the end of the text and working
backwards.
The
Friedman’s, in their The Shakespeare Ciphers Examined, had this to say
of acrostics: “Acrostic devices have the advantage that, unlike ciphers which
depend on accidents of page-numbering or particular kinds of type, they leave
no doubt that the author of the open text must also have been responsible for
any hidden message—once it is established that one exists.” ”If, therefore,
any genuine messages of this kind exist, they must be taken as
conclusive.” About Elizabethan acrostics they write “Certainly, they were
very popular at the time. Walsh, in his Hand-Book
of Literary Curiosities, comments that the business of composing acrostics
‘was carried to its most ridiculous and wasteful excess by the Elizabethan
poets’.” They give some examples. One has the name of spymaster Sir
Francis Walsingham’:
Shall Honour, Fame, and Titles of
Renowne,
In Clods of Clay be thus inclosed still?
Rather will I, though wiser Wits may frowne,
For to inlarge his Fame extend my skill.
Right, gentle Reader, be it knowne to thee,
A famous Knight doth here interred lye,
Noble by Birth, renowned for Policie,
Confounding Foes, which wrought our Jeopardy.
In Forraine Countries their Intents he knew,
Such was his zeal to do his Country good,
When Dangers would by Enemies ensue,
As well as they themselves, he understood.
Launch forth ye Muses into Streams of Praise,
Sing, and sound forth Praise-worthy Harmony;
In England Death cut off his dismall Dayes,
Not wronged by Death, but by false Trechery.

Grudge not at this imperfect
Epitaph;
Herein I have exprest my simple Skill,
As the First-fruits preceding from a Graffe:
Make then a better whosoever will.

The RED-BOLD
was added for this example and was not part of the original form.
