Palazzo Donà della Madonnetta at San Polo 1429, Nadali & Vianello (1999) Tav. 29, in 1849 the house of the Prefect of Police, is cited by Ruskin in the Appendix at Works, 10.453ff as an example of Byzantine architecture. See House Book 1 pp.36L and 36 and the note there, and compare House Book 2 p.47L.
There are references to it at Notebook M p.82; Notebook M p.83; Notebook M2 p.5L; Notebook M2 p.54 on the development of capitals; Notebook M2 p.97; and at Works, 11.277 on the leafage of the capitals.
At Works, 10.454 Ruskin oddly says: ‘I shall call it, from the name of its Traghetto, the Madonnetta House’. He ignores the obvious explanation for the name, the relief of the Madonna on its façade.
