sororium

Updated: May 6, 2025

This beam long survived under the name of Tigillum Sororium or Sister's Beam, and was constantly repaired at the public expense. In modern times there are two most remarkable survivals of the same kind. One of them is in the corridor of the mosque of Aksa at Jerusalem.

He, having offered certain expiatory sacrifices, which were ever after continued in the Horatian family, and laid a beam across the street, made his son pass under it as under a yoke, with his head covered. This remains even to this day, being constantly repaired at the expense of the public; they call it Sororium Tigillum.
