The use of thin sheets of lead to write on was quite common in the Iberian world, as in the Greek and Roman worlds. Although the Iberian inscriptions cannot be deciphered, these texts are thought to be letters, sacrificial texts or offerings, or accounting documents. The lead from the Castle at La Fosca is inscribed with symbols arranged in straight lines, although they increase slightly in size lower down. You can see the separation of words by groups of three dots in a vertical position. It is by far the longest inscription in the Iberian language from Catalonia.
