The kind of door to which these mouldings belong, is shown, with the other groups of doors, in [Plate XIV.] Vol. II. fig. 6 a. Then 6 b, 6 c, 6 d represent the groups of doors in which the Byzantine influence remained energetic, admitting slowly the forms of the pointed Gothic; 7 a, with the gable above, is the intermediate group between the Byzantine and Gothic schools; 7 b, 7 c, 7 d, 7 e are the advanced guards of the Gothic and Lombardic invasions, representative of a large number of thirteenth century arcades and doors. Observe that 6 d is shown to be of a late school by its finial, and 6 e of the latest school by its finial, complete ogee arch (instead of round or pointed), and abandonment of the lintel.
These examples, with the exception of 6 a, which is a general form, are all actually existing doors; namely:
6 b. In the Fondamenta Venier, near St. Maria della Salute.
6 c. In the Calle delle Botteri, between the Rialto and San Cassan.
6 d. Main door of San Gregorio.
6 e. Door of a palace in Rio San Paternian.
7 a. Door of a small courtyard near house of Marco Polo.
7 b. Arcade in narrow canal, at the side of Casa Barbaro.
7 c. At the turn of the canal, close to the Ponte dell’ Angelo.
7 d. In Rio San Paternian (a ruinous house).
