Various conflagrations, in addition to the growing needs of the State, led to rebuilding and enlargement. The first wing was added in the twelfth century, when the basement and first floor of the portion from the Porta della Carta to the thick seventh column from the Adam and Eve group, under the medallion of Venice, on the Piazzetta façade, was set up, but not in the style which we now know. That was copied three centuries later from the Riva or lagoon façade. In 1301 the hall above the original portion on the Rio del Palazzo side, now called the Sala del Senato, was added and the lagoon wing was rebuilt, the lower arches, which are there to-day, being then established. A few years later, a still greater hall being needed, the present Sala del Maggior Consiglio was erected, and this was ready for use in 1423. The lagoon façade as we see it now, with its slender arches above the sturdy arches, thus dates from the beginning of the fifteenth century, and this design gave the key to the builders of later Venice, as a voyage of the Grand Canal will prove.
It was the great Doge Tommaso Mocenigo (1413-1423) who urged upon the Senate the necessity of completing the palace. In 1424 the work was begun. Progress was slow and was hindered by the usual fire, but gradually the splendid stone wall on the Rio del Palazzo side went up, and the right end of the lagoon façade, and the Giants' Stairs, and the Piazzetta façade, reproducing the lagoon façade. The elaborately decorated façades of the courtyard came later, and by 1550 the palace was finished. The irregularity of the windows on the lagoon façade is explained by this piecemeal structure. The four plain windows and the very graceful balcony belong to the Sala del Maggior Consiglio. The two ornate windows on the right were added when the palace was brought into line with this portion, and they are lower because the room they light is on a level lower than the great Council Hall's. The two ugly little square windows (Bonington in his picture in the Louvre makes them three) probably also were added then.
When the elegant spired cupolas at each corner of the palace roof were built, I do not know, but they look like a happy afterthought. The small balcony overlooking the lagoon, which is gained from the Sala del Maggior Consiglio, and which in Canaletto and Guardi's eighteenth-century pictures always, as now, has a few people on it, was built in 1404. It is to be seen rightly only from the water or through glasses. The Madonna in the circle is charming. She has one child in her arms and two at her knees, and her lap is a favourite resting-place for pigeons. In the morning when the day is fine the green bronze of the sword and crown of Justice (or, as some say, Mars), who surmounts all, is beautiful against the blue of the sky.
The Piazzetta façade balcony was built early in the sixteenth century, but the statue of S. George is a recent addition, Canova being the sculptor.
Now let us examine the carved capitals of the columns of the Ducal Palace arcade, for these are extremely interesting and transform it into something like an encyclopedia in stone. Much thought has gone to them, the old Venetians' love of symbols being gratified often to our perplexity. We will begin at the end by the Porta della Carta, under the group representing the Judgment of Solomon—the Venetians' platonic affection for the idea of Justice being here again displayed. This group, though primitive, the work of two sculptors from Fiesole early in the fifteenth century, has a beauty of its own which grows increasingly attractive as one returns and returns to the Piazzetta. Above the group is the Angel Gabriel; below it, on the richly foliated capital of this sturdy corner column, which bears so much weight and splendour, is Justice herself, facing Sansovino's Loggetta: a little stone lady with scales and sword of bronze. Here also is Aristotle giving the law to some bearded men; while other figures represent Solon, another jurist, Scipio the chaste, Numa Pompilius building a church, Moses receiving the tables of the law, and Trajan on horseback administering justice to a widow. All are named in Latin.
The second capital has cherubs with fruit and birds and no lettering.
The third has cranes and no lettering.
The fourth is allegorical, representing, but without much psychology, named virtues and vices, such as misery, cheerfulness, folly, chastity, honesty, falsehood, injustice, abstinence.
The fifth has figures and no lettering. A cobbler faces the campanile. It is above this fifth column that we notice in the upper row of arches two columns of reddish stain. It was between these that malefactors were strangled.
The sixth has symbolical figures which I do not understand. Ruskin suggests that they typify the degradation of human instincts. A knight in armour is here. A musician seated on a fish faces the Old Library. There is no lettering, and as is the case throughout the figures on the wall side are difficult to discern.
