The door of San Sigismondo is too interesting, especially the rings, the dove and the dog.

1. Bordigallo. "Cronica cremonese".
Probabilly:
Domenico Bordigallo. (Cremona 1449-1527?), Cronica a principio mundi ad annum 1527, ms. sec. XV (Cremona, Biblioteca Statale, ms. 264). Probabilly the main source about "carri alleorici di Zanino e Berta". We must be found.

The Cronica a principio mundi ad annum 1527, is not published. But Raffaella Barbierato , of Biblioteca Statale di Cremona (BSCr), send me a copy whit the part of marriage. She is vey friendly:
