Biblical languages are any of the languages employed in the original writings of the Bible.Some debate exists as to which language is the original language of a particular passage, and about whether a term has been properly translated from an ancient language into modern editions of the Bible.
In the original chart by Trithemius, the letter W comes after Z, as it was a recent addition to the Latin alphabet, and did not yet have a standard position. This caused it to be misinterpreted as an ampersand [ 6 ] or end-of-sentence mark [ 7 ] by later translators and copyists, such as Francis Barrett .
The Atbash cipher is a particular type of monoalphabetic cipher formed by taking the alphabet (or abjad, syllabary, etc.) and mapping it to its reverse, so that the first letter becomes the last letter, the second letter becomes the second to last letter, and so on. For example, the Hebrew alphabet would work like this:
The tap code is based on a Polybius square using a 5×5 grid of letters representing all the letters of the Latin alphabet, except for K, which is represented by C. . Each letter is communicated by tapping two numbers, the first designating the row and the second (after a pause) designating the column.

In the following examples, two cipher texts contain the same message. They are constructed from the example grille, beginning in the NORTH position, but one is formed by rotating the grille clockwise and the other anticlockwise. The ciphertext is then taken off the grid in horizontal lines - but it could equally be taken off vertically. CLOCKWISE
Tabula recta. In cryptography, the tabula recta (from Latin tabula rēcta) is a square table of alphabets, each row of which is made by shifting the previous one to the left.. The term was invented by the German author and monk Johannes Trithemius [1] in 1508, and used in his Trithemius ciph
