Waar dient het deurtje voor en wat betekent de afkorting O.S.I.?
De foto is genomen in de Cattedrale San Lorenzo van Lugano.
Volgens mij is dit een tabernakel, de kluis in de kerk waar de geconsacreerde hostie wordt bewaard. De afkorting ken ik niet
The Rodari Tabernacle, c. 1510, built to house the Reserved Sacrament and became later tabernacle to the holy anointing oil as appears from "O.S.I." (Oleum Sanctum Infirmorum), inscribed at the original gilded iron door.
The wall tabernacle, originally placed in the great chapel, is ascribed to Tommaso Rodari (1460-1526) of Maroggia (village at Lake Lugano), best known as sculptor and master builder of the Cathedral of Como, Italy.
The design of the tabernacle is equivalent to this of a triptych. The central panel is separated from the wings by Corinthian pilastres. In the left and the right wings are the holy deacons: St Lawrence with a grid, and St Vincentius with a millstone. I the central panel two angels guard the tabernacle door and in the ceiling is God the Father with his right hand raised in blessing. At the top of the tabernacle is The Risen Christ, a copy from 1908 of the original statue.
