Cornerstone

In modern Greece, when the foundation of a new building is being laid, it is the custom to kill a cock, a ram, or a lamb, and to let its blood flow on the foundation-stone, under which the animal is afterwards buried.

[3] Ancient Japanese legends talk about Hitobashira (人柱, "human pillar"), in which maidens were buried alive at the base or near some constructions as a prayer to ensure the buildings against disasters or enemy attacks.

After this, Bishop Gregg spread cement over the stone with a trowel specially made for the occasion by John Hawkesworth, a silversmith and a jeweller.

The Deputy Provincial Grand Master of Munster poured offerings of corn, oil and wine over the stone after Bishop Gregg had declared it to be 'duly and truly laid'.

The Provincial Grand Chaplain of the Masonic Order in Munster then read out the following prayer: 'May the Great Architect of the universe enable us as successfully to carry out and finish this work.

May He protect the workmen from danger and accident, and long preserve the structure from decay; and may He grant us all our needed supply, the corn of nourishment, the wine of refreshment, and the oil of joy, Amen.

[6] Normally, a VIP of the organization, or a local celebrity or community leader, will be invited to conduct the ceremony of figuratively beginning the foundations of the building, with the person's name and official position and the date usually being recorded on the stone.

Once preparations have been made, the bishop—or a priest delegated by him for that purpose—will bless holy water and with it sprinkle first the cross that was erected and then the foundation stone itself.

Upon the stone he is directed to engrave crosses on each side with a knife, and then pronounce the following prayer: "Bless, O Lord, this creature of stone (creaturam istam lapidis) and grant by the invocation of Thy holy name that all who with a pure mind shall lend aid to the building of this church may obtain soundness of body and the healing of their souls.

Then the bishop, if he deems it opportune, sits down and exhorts the people to contribute to the construction, appointments and maintenance of the new church, after which he dismisses them with his blessing and the proclamation of an indulgence.

After the foundations for the new church have been dug and all preparations finished, the bishop (or his deputy) with the other clergy vest and form a crucession to the building site.
