Who put the alphabet in alphabetical order?

The earliest evidence of letter order is from Ugarit, circa 13th century BCE.

There were two main alphabets, consisting of 22 and about 30 letters.

The 22-letter alphabet was adopted by the Phoenicians & Hebrews and

the order of letters has persisted as the basis of Latin derived alphabets

into the present: A B G D H V.. A B C D E F..

The principles originally employed in ordering the letters are phonemic,

based on where the consonants were articulated in the buccal cavity

(mouth & throat). But the ordering system is complex - not 1 2 3 / A B G.

It is based on geometry, with the 22 letters arranged in a circle, equally

spaced. Similar letters are grouped in sets of four, forming rectangles with

the Alef axis intersecting all of them, and linked with the back-of the-throat

phonemes to create a hexagram or 'Star Of David'.

Clues to this a pattern can be found in the oldest extant versions (2nd

century CE) of the Qabalistic text, 'Sefer Yetzirah'.

The order of the letters was of great religious significance, although beliefs

and philosophy changed over time, along with how some of the letters were

pronounced.
