To some degree, exceptionally short pieces of textual evidence in Celtiberian also allow to gain some information about what possibly could have been a widespread Celtic legal practice. From Spain, a number of so-called tesserae hospitales, 'hospitality tablets', are known, inscribed in Celtiberian, often with no more than a single word, occasionally with very short sentences. These may indicate a custom of granting hospitality to foreigners, which may have had a basis in customary law and may have allowed to grant legal protection to foreigners, as also found in many other Indo-European societies and the early Irish and Welsh laws.
