Out of numerous Venetianarchitecture, Ruskin described St. Mark’s Basilica as “the most perfectByzantine type” (1853, p.215).
This cathedral has been through three times ofreconstruction since 828 and the addition of its oriental architecturalqualities was significantly due to the conquest of Constantinople in the 1204. Ruskin first pointed out the marble claddingof St. Mark’s by specifying the difference between the Northern and the Southernconstruction systems. The sculptural ornament of the former one was the samematerial as the masonry wall, like the Gothic cathedrals in England; whereas thelatter creates a “duplicity” (1853, p.77) by covering the structural brickworkswith decorative thin marble cladding in fig.1, which is the quality of Byzantinearchitecture that St.
Mark’s has. Nevertheless, Ruskin stated that the shaft ofall the excessive pillars are solid as “the Byzantine is allowed to have asmuch support as he wants from the walls in every direction” (1853, p.82). The accessibilityof Venetian to “the riches in Asia and the quarries in Egypt”(1853, p.
82) also benefited this kind of building method.
