OUMNH Number: 99  
Name and quarry location: Marmo Greco scritto from Capo de Garde, Annaba (Hippo Regius), Algeria  
Geological description: A deformed, medium to coarse-grained calcite marble. A tectonite showing linear shear fabric. The dark grey graphite-rich zones result from the deformation of a breccia or vein system rather than a colour-banded rock.  
Comments: This appears to be Greco scritto from the ancient city of Hippo Regius in Algeria, a stone that was worked particularly between the first and third centuries AD. The name Greco scritto, used by the scalpellini, alludes to the almost black markings looking like Greek letters, although at other orientations, they are seen to be joined. Corsi's sample is too coarse-grained to be a bardiglio from the Apuan Alps of Italy, which can otherwise appear similar.
