Edward Clodd,
The Story of the Alphabet
“ But man at the same stage of culture being everywhere practically the same, there is, in the paucity of examples from the Europe of the past, compensation in the specimens of graphic art found among extant barbaric folk. It is probable that a good proportion of these lack significance, but the pictograph is the parent of the alphabet, and therefore the careful transcripts of rock and other paintings which explorers have made may yet prove to be of value when interpreted in the light of examples whose gradations have been traced. ”
