Simple bases supported monolithic shafts, spaced 5.77 meters apart. The shafts supported Byzantine-style Corinthian capitals – intricately carved, but more stylized versions of their Classical counterparts. Although this combination of elements was uniform the preserved examples display some variation in the profile and size of the bases, and in the pattern of the capitals. Despite aesthetic differences, the approximate height of the base, column, and capital units of the colonnade was five meters, a height which contributed to the spaciousness of the porticoes. The wall of the Cardo's eastern portico featured an arcade that housed various stalls and workshops leased by craftsmen and merchants.
