How woud an attack work? Spiral text as Rev. 6:14.

[MarcoP]

I experimented with various transliterations and various plain-text passages.

The input EVA sequence I use in this example is (where 'b' stands for the initial '/'):

oboas,oetchy osas,aram askeeody ochdor,al oekairy ytodaro opalshy orarodar yky,dar ykodar ykary opalxy

The following is a homophonic verbose cipher that maps to these words from Wycliffe's translation You are not allowed to view links. Register or Login to view.:

Spaces were ignored in both the cipher-text and plain-text.

Deciphered text:

Of course, this only shows that a short passage in combination with complex cipher systems does not allow an unambiguous solution.
