At the apsis of a small church of Salamis, Cyprus, a metrological relief showing units of measure has been recognized by the author. In addition to a rule, it shows a foot, a cubit, a hand, an arm, and part of a head. Two different units of length were identified: 0.322 m and 0.301 m. This is the second relief of its kind to have been identified; the other is now at the Ashmolean Museum, Oxford.
