Note 43 — Chapter IV · CENTRAL MEDIÆVAL DESIGN
Reading edition
Thermæ: In Latin an establishment for warm baths: a plural noun used for a single building or group of buildings. The Thermæ of Caracalla mentioned in this chapter, occupied all the space within a bounding wall which formed a square of 1,100 feet (about twenty-eight acres) and within this were gardens, running grounds and the like, and among these the massive central building itself, 400 × 750 feet, twice the space occupied by the capitol at Washington, which is also immeasurably less massive and permanent in structure.
