which language it could be ?

[VVV]

Here I found a short explanation in French, too.
It's from Doutté and the square with the seals in is a version of the Latin square where, usually a formula or passage from the Qur'an, is repeated in such a way that the same symbol/word only occurs once in each direction.
If you combine the table from Canaan with the explanation from Doutté I think you will get most of it...
