The aim of the paper is to present some of the principal areas of progress achieved in the hermeneusis of the 'Tabula Cortonensis' in recent years. The authors interest pivots particularly arround Etr. 'sparza', a key-word of the text. A new interpretation pattern (for the first time acceptable both on a lexical and on a morpho-syntactical level of analysis), proposed by Ignasi Adiego, reveals his full correctness, save for some minor details: so we are allowed to fix the meaning of this word definitively as 'tablet'. This acquisition displays some remarkable implications that will be further examined in future works.
