Between 1173 and the close of the century, it seems to have been again repaired and much enlarged by the Doge Sebastian Ziani. Sansovino says that this Doge not only repaired it, but "enlarged it in every direction;" [Footnote: "Non solamente rinovo il palazzo, ma lo aggrandi per ogni verso."--_Sansovino_. Zanotto quotes the Altinat Chronicle for account of these repairs.] and, after this enlargement, the palace seems to have remained untouched for a hundred years, until, in the commencement of the fourteenth century, the works of the Gothic Palace were begun. As, therefore, the old Byzantine building was, at the time when those works first interfered with it, in the form given to it by Ziani, I shall hereafter always speak of it as the _Ziani_ Palace; and this the rather, because the only chronicler whose words are perfectly clear respecting the existence of part of this palace so late as the year 1422, speaks of it as built by Ziani. The old "palace of which half remains to this day, was built, as we now see it, by Sebastian Ziani." [Footnote: "El palazzo che anco di mezzo se vede vecchio, per M. Sebastian Ziani fu fatto compir, come el se vede."--_Chronicle of Pietro Dolfino_, Cod. Ven. p. 47. This Chronicle is spoken of by Sansovino as "molto particolare, e distinta."--_Sansovino, Venezia descritta_, p. 593.--It terminates in the year 1422.] So far, then, of the Byzantine Palace. SECTION XII. 2nd. The GOTHIC PALACE. The reader, doubtless, recollects that the important change in the Venetian government which gave stability to the aristocratic power took place about the year 1297, [Footnote: See Vol. I. Appendix 3, Stones of Venice.] under the Doge Pietro Gradenigo, a man thus characterized by Sansovino:--"A prompt and prudent man, of unconquerable determination and great eloquence, who laid, so to speak, the foundations of the eternity of this republic, by the admirable regulations which he introduced into the government." We may now, with some reason, doubt of their admirableness; but their importance, and the vigorous will and intellect of the Doge, are not to be disputed. Venice was in the zenith of her strength, and the heroism of her citizens was displaying itself in every quarter of the world. [Footnote: Vide Sansovino's enumeration of those who flourished in the reign of Gradenigo, p. 564.] The acquiescence in the secure establishment of the aristocratic power was an expression, by the people, of respect for the families which had been chiefly instrumental in raising the commonwealth to such a height of prosperity. The Serrar del Consiglio fixed the numbers of the Senate within certain limits, and it conferred upon them a dignity greater than they had ever before possessed. It was natural that the alteration in the character of the assembly should be attended by some change in the size, arrangement, or decoration of the chamber in which they sat.
