[Footnote 1: We may compare with Venice what is known about the ancient Hellenic city of Sybaris. Sybaris and Ravenna were the Greek and Roman Venice of antiquity.] [Footnote 2: His first wife was a daughter of the great general of the Venetians against Francesco Sforza. Whether Sigismondo murdered her, as Sansovino seems to imply in his _Famiglie Illustri_, or whether he only repudiated her after her father's execution on the Piazza di San Marco, admits of doubt. About the question of Sigismondo's marriage with Isotta there is also some uncertainty. At any rate she had been some time his mistress before she became his wife.] [Footnote 3: For the place occupied in the evolution of Italian scholarship by this Greek sage, see my 'Revival of Learning,' _Renaissance in Italy_, part 2.] [Footnote 4: The account of this church given by Æneas Sylvius Piccolomini (Pii Secondi, Comment., ii. 92) deserves quotation: 'Ædificavit tamen nobile templum Arimini in honorem divi Francisci, verum ita gentilibus operibus implevit, ut non tam Christianorum quam infidelium dæmones adorantium templum esse videatur.'] [Footnote 5: Almost all the facts of Alberti's life are to be found in the Latin biography included in Muratori. It has been conjectured, and not without plausibility, by the last editor of Alberti's complete works, Bonucci, that this Latin life was penned by Alberti himself.] [Footnote 6: There is in reality no doubt or problem about this Saint Clair. She was born in 1275, and joined the Augustinian Sisterhood, dying young, in 1308, as Abbess of her convent. Continual and impassioned meditation on the Passion of our Lord impressed her heart with the signs of His suffering which have been described above. I owe this note to the kindness of an anonymous correspondent, whom I here thank.] [Footnote 7: The balance of probability leans against Isabella in this affair. At the licentious court of the Medici she lived with unpardonable freedom. Troilo Orsini was himself assassinated in Paris by Bracciano's orders a few years afterwards.] [Footnote 8: I have amplified and corrected this chronicle by the light of Professor Gnoli's monograph, _Vittoria Accoramboni_, published by Le Monnier at Florence in 1870.] [Footnote 9: In dealing with Webster's tragedy, I have adhered to his use and spelling of names.] [Footnote 10: The fresco of the Coronation of the Virgin upon the semi-dome of S. Giovanni is the work of a copyist, Cesare Aretusi. But part of the original fresco, which was removed in 1684, exists in a good state of preservation at the end of the long gallery of the library.]
