Early theories proposed a pictographic-acrophonic origin for the Brahmi script, on the model of the Egyptian hieroglyphic script. These ideas however have lost credence, as they are "purely imaginative and speculative". Similar ideas have tried to connect the Brahmi script with the Indus script, but they remain unproven, and particularly suffer from the fact that the Indus script is as yet undeciphered.
