On October 17, the first 10 of the 20 marble columns slated for the nave of the Chapel arrived from Italy and were unloaded near the construction site. Cut from solid blocks of marble, shaped on a lathe, and polished to a luminous sheen, these graceful columns will be the most prominent visual element of the nave, and will serve to march the eye down the central nave to the altar and tabernacle centrally located in the sanctuary. Choosing the Material Though marble has long been the material of choice for church builders, its geological delicacies can make it a difficult medium to manipulate. For example, the initial cut of any block of marble can reveal fissures and cracks, making it a poor candidate for a column. As a consequence, most of the blocks quarried for the Chapel (average size of 15 x 5 x 5 and weight in excess of 34 tons) yielded as many as four columns, while from a few, our marble manufacturer in Pietrasanta, Savema, was only able to harvest two. Little marble is actually wasted though, as cracked marble that may not be suitable for 14 columns can still be used for other projects. Designing the Columns
The columns are tapered in the traditional style of the Greeks and the Romans and weigh approximately 3,260 pounds each. As in the classical tradition, the lower third of the column is cylindrical, while the top two-thirds tapers along a curved profile as it rises to the neck. Architect Stroik explains, This technique is called entasis, and its purpose is to give the columns visual strengthan imitation of the way a person or a tree is stouter at the base than at the top. Compare a classical column with entasis to a purely cylindrical, functional, round column without it and you can see the difference. As columns get larger the amount of entasis gets smaller, since natural perspective helps give a sense of this vertical transition. The columns of Our Lady of the Most Holy Trinity Chapel are 1-7 in diameter at the base, and 1-4 1/2 in diameter at the neck, a 2 1/2 difference in diameter. The bases for the columns will be made of Calacatta Apuano marble, lighter in color than the Botticino columns, providing a subtle contrast of hues. The custom Corinthian capitals will be faux-painted plaster to match the bases as is traditional in many churches in Rome and in America. This technique allows the artisan to carve only one or two capitals and then reproduce others through a sophisticated casting process. Dr. Dillons Role Due to the demands of the Chapels construction schedule, the columns will be set in place within the interior of the Chapel prior to the construction of its roof and ceiling, an event for which design architect Stroik will be on hand. To protect the columns during the on-going construction, steel rods will be set in concrete around each column, to be removed during the final phase of building. As the arrival of the columns indicates, construction of Our Lady of the Most Holy Trinity Chapel is steadily progressing. There remain numerous opportunities for individual friends of the College to participate in the funding of these columns. Gifts large and small are being received from generous benefactors and the College is most thankful for them. You are invited to add your gift to theirs, to help fully fund the columns of the Chapel.
