This is one of the inscriptions listed by McManus (1991, 94-5) in which apocope (loss of final consonants or syllables) begins to show itself (CUNOVATO (earlier -os). 'The final S has been dropped but lowering has not taken place in the first syllable'. On this basis it may be dated to the first half of the sixth century (McManus 1991, 97, 176 note 40). However, although Macalister (1945, 16) notes that the inscription 'seems to be complete', an original CUNOVATOS is possible considering that the end of the stone is fractured. This would make the estimated date even earlier.
