Fragment of relief with Isiac scene

This panel presents decorations on three registers. On the lowest register a row of ibises evokes a Nile landscape. At the centre is a scene of music and dancing, perhaps connected with the Navigium Isidis, a festival held on March 5th when navigation resumed after the winter. On the top frieze some gods are placed within shrines whilst the sacred bull Apis stands on a podium outside the portico. The relief, dated to 100 AD, may portray the courtyard of the Iseum and Serapeum in the Campus Martius.
