Delphi Tablet I

This inscription is #5678 in the Museum of Delphi, Greece. It is part of a collection of pieces found in the Temple of Apollo dated in the third century BC. The first two pieces in this set were found by a French archeological dig in 1893 and the last were found in 1929.

The symbols in the table are not identified in the book I am reading and I have found no reference on the internet. Within the small table are two shapes in three orientations organized in descending columns while the another shape occurs in four orientations. Two other single shapes occur.

The first line below the table starts "TA ANO GRA.." possible GRAMMATA, or letters. After that follows a phonetic organisation of Greek consonants which I am going to set off in groups with spaces between.

ΓΔΒ ΚΤΠ ΛΝ...
ΓΔΒ ΧΦΘ Λ... (the first set of three letters and Λ are modified with a dot)

English
GDB KTP LN...
GDB CH TH PH L...

The following rows continue the pattern with alterations to the letters.

This tablet indicates the antiquity of the phonetic organization of the Greek consonants. I am not able to comment on the purpose of this tablet.

Errata: In the table there are actually three different shapes that occur in three orientations and three single shapes.
