Nativity Scene at the church of Santa Maria del Giglio (Santa Maria Zobeningo). You can see how it is partly covered with a cloth, to be taken off only on Christmas Eve
They tell about life, reality and dreams ... and take Venetians back to their roots ... that's the special meaning behind Nativity Scenes that you see in the Venetian homes and churches, practically everywhere ... even in pastry stores.

I publish this article in time for January 6, which is the REAL Christmas Festivity day, the ancient, traditional one celebrated in Venice. And it's the day when you should make sure to take a closer look at the Torre dell'Orologio (Bell Tower) in Piazza San Marco ...  
The Piazza with the outside tables of Caffé Lavena, and the Torre dell'Orologio which plays a major part in Venice on January 6
January 6 is dedicated to the the Re Magi - Wise Men - visiting the presepio (Nativity Scene). On the other hand, this is the time when Befana visits Venetian homes and brings little presents to children (also to adults, thanks to our pastry stores). Children in Venice hang up stockings on the evening of January 5 - much like is done with Santa Clause in other countries - and in the morning of January 6, these stockings are filled with little presents, usually sweets - like il carbone della Befana (cookies - which will be described in my blog on Breakfast in Venice - Colazione A Venezia, with Befana and the Roghi - wood fires built of cataste di legna in the Veneziano (Province of Venice) to be able to tell the future from the direction the smoke takes ...

Nativity scenes are an important piece of reminscence of the past in the campagna veneta - the Venetian countryside, as the mainland bordering the lagoon around Venice is referred to by Venetians ... and reflect the sageness of life in the country, plus the forgotten knowledge and mores of those days (there is, though, a calendar called Cronaca Barbanera reflecting and collecting this ancient knowledge).
Presepio privato - Nativity Scene in a private home in Venice
Last year I came across a story published in the Gente Veneta Magazine, on how children in the Veneto used connect to Nativity scenes ... told in a book "Ricominciamo da Gesù" by Gianni Ferraresi, published by Marcianum Press.
Excerpt from the Book on Nativity Scenes Creating and childhood memories in the Veneto by Gianni Ferraresi
In the book you can read how Venetians adore creating their presepi, they love creating landscapes, and they start doing that well ahead of Christmas. Children were gently led by parents in the discovery of life - so my grandmother told me, to get creative and make up the presepi with what was available. The children who were allowed to create the Nativity Scene were actually proud to do so.

Venetian children these days (me too, when I was a child) get Christmas books to learn about the history of presepi, and usually parents buy them at Libreria Studium next to the Piazza.
The bookshop offers do-it-yourself-templates of Nativity Scenes and lots of colorful magical books ... enlarging the horizon of children and adults alike as you can train and express yourselves in setting a stage ..

So Venetians, like the people in other regions in Italy, reflect their everyday environment, homes and essentials of daily life into a miniature edition - their presepi. Though, compared to Nativity Scenes from Naples, Venetians include more elements of the original setting and nature in Bethlehem. Neapolitan cribs include every detail of daily life in Naples in a fantastic, artistic composition.

On January 6, il giorno dell'Epifania, the Nativity Scenes become complete ... as the Re Magi, the wise men from the East, arrive, led by their Stella di Betlemme (Star of Bethlehem). 
Adorazione dei Magi - Niccolò Bambini 1717, Church of San Zaccaria, Venice
In many Venetian churches, this adorazione dei Re Magi (adoration) is expressed by paintings, like the one shown in the picture above in the Church of San Zaccaria, which is just round the corner from my home.

It's January 6 that you shouldn't miss in Venice, it's not just because of the Befana tradition, the sweet coal she brings, but it's a special greeting  - adoration of the Madonna e Bambino by the Re Magi that is seen on this day in Venice, at the Torre dell'Orologio - and here it is, in the picture below:
Look up at the Torre dell'Orologio (here I am standing on the Platform next to the Christmas tree to take the picture). Just above the clock you can see is a statue of Madonna and Child. It is here that the Re Magi will greet them at every full hour.
Here is a video to show you the spectacle. By the way, you can visit the Torre dell'Orologio, and can even reach the platform where the two mori striking the clock are located. During your visit to the Bell Tower, you will be shown these four figures (angel and the three Re Magi) as they wait for their appearance, which taks place just twice a year - on January 6 and on 15 August.
Privately, January 6 is another morning traditionally begun with eating Pinsa veneta for breakfast - we also do that on 24 December ... here is our pinsa - a sweet polenta cake filled with dried fruit:

Buona Epifania a Tutti !!
