49, Milan, Sant’Ambrogio, study of south elevation of easternmost bay of nave, with details
Inscribed ‘S. AMBROGIO MILAN’, with other notes in pencil, 230x160mm.
The three-aisled Lombard Romanesque basilica of Sant’Ambrogio was consecrated by Saint Ambrose, Bishop of Milan, in 386. The structural form of the nave, each bay of which is identical, dates from the late twelfth century. The three westernmost bays have rib vaults, the easternmost, drawn by Mackintosh, has a dome on squinches. He described Sant’Ambrogio as ‘a quaint old thing in stone brick and plaster’ (‘Diary’, 28 June).
The drawing indicates: a squinch (top left); elevation of a bay (centre); plan of a pier showing the arrangement of the vaulting (bottom).
