As Cecilia Powell first identified,1 the subject of these two sketches is the so-called Temple of Diana, a Roman bath-house with a vaulted half-dome roof which is one of a number of ruined buildings in the ancient bathing resort of the Bay of Baiae.2 Further studies can be found on folios 80 verso, 85 and 92 (D15714, D15723 and D15737; Turner Bequest CLXXXIV 78a, 83 and 90). The ruin features in Turner’s later oil painting, The Bay of Baiae, with Apollo and the Sibyl exhibited 1823 (Tate, N00505).3
