What do you mean by ‘depict’? ‘Decipher’? ‘Reconstruct’? Those are quite different questions!
Decipherment is done by using bilingual texts and transcriptions of personal names, with reference to related languages if there’s any known or suspected to be related. Reconstruction is done by comparing modern descendant languages (and attested older forms when available) and seeing how the differences between them could have developed through natural language change.
