The Basilica of Sant'Ambrogio is a church in the center of Milan, northern Italy. The basilica has a semi-circular apse, and smaller, semi-circular chapels at the end of the aisles; there is no transept. The interior has the same size as the external portico. The ceiling features groin vaults with ogives, each supported by its own semi-pillar or semi-column, which, in the lower section, become a single pillar. The aisles' spans measure exactly half of those in the nave and are supported by lesser pillars. The matronei (galleries) over the aisles support the vaults but preclude clerestory windows. The third central span, on the left, houses the 12th century Romanesque ambon or pulpit, built on a pre-existing 9th century one; which utilizes as a base a 4th-century Roman sarcophagus, traditionally known as the Sarcophagus of Stilicho. It has nine small columns with decorated capitals and friezes, featuring animal and human figures, as well as vegetable and fantastic motifs. The front of the ambon is decorated by two gilt copper reliefs, depicting the symbols of two evangelists, Saints Matthew (praying man) and John (eagle). https://en.wikipedia.org/wiki/Basilica_of_Sant%27Ambrogio
