Abstract
The stele of Axum was brought to Rome in 1937, broken in five pieces. The erection of the stele in Rome, in Porta Capena square, required re-joining the pieces with mortar joints and bronze bolts. To give back the stele to the Ethiopian authorities, following an Italian/Etiopian agreement, it was impossible to send the stele as it was, it required separation into three pieces so that the load and dimension of each piece was compatible with the aircraft characteristics. This operation was very delicate, as for cultural reasons it was not acceptable to cut the stone (granite) of the stele with a saw; therefore the only option was to disarticulate the stele in two of the joints. To do that, as the material was weakened by microcracks and decay, it was foreseen to provisionally protect the stone with a carbon-fibre and epoxy fabric and then to apply tension forces to open the joints with a system of jacks.
