The Cradle of Genius

Leonardo da Vinci's childhood homes:
Anchiano and Vinci
 
Leonardo da Vinci bequeathed us two anecdotes concerning his childhood: ostensibly memories, it has been argued that they might be parables or accounts of dreams.
Vinci
The first involves a bird. Flight always fascinated Leonardo da Vinci: many pages in his notes and 500 sketches are dedicated to the study of birds' wings, including experiments real and hypothetical with potential flying machines, (the ornithopter being the most spectacular), parachutes, ascending devices and keen observations on the gliding flight of birds.

The Moroccan Wall

At last, a drystone wall!

after: the completed wall and earthworks

before: the crumbling old wall, seen behind the line of the broom plant with new stones piled in front

In his The Stone Book Quartet, Alan Garner evokes the art of making a drystone wall in language as essential as dressed stone.

Grandfather was rough-dressing the stone for the wall, and laying it out along the hedge. Joseph unwound the line and pegged one end in the joints where Grandfather had finished the day before, and pulled the line tight against the bank. His job was to cut the bank back to receive the stone and to run a straight bed for the bottom course.
He chopped at the bank.
...
'Get your knee aback of your shovel,' said Grandfather. 'There's no sense in mauling yourself half to death. Come on, youth. Shape!'
...
Grandfather took the spade from him and looked along the bank. He walked along the raw cut edge and shaved the earth with light swings of the blade.'You've got it like a fiddler's elbow,' he said.
...
Grandfather grunted, and swung the blocks to lie as he wanted. They seemed to move without more than his hand on them.
...
Grandfather and Damper Latham worked together, as they had always done. The stone moved lightly for them.

Subterranean Siena

A walk beneath Siena to explore its medieval waterworks


In a hilltop town which lacks a natural spring, where does the water in that fountain come from?

Walking around Siena one happens on a variety of medieval wells. Yet Siena is not naturally rich in water: it is a hilltop settlement and situated far from the great rivers of Tuscany. Until World War I the city relied on a water supply system constructed in the Middle Ages: 25 kilometres of channels and side-channels, an underground aqueduct winding under the entire city. They are called the bottini, a name perhaps related to the barrel shape of the passages, botte being barrel.

The Art of Fresco part one: Masaccio, the Brancacci Chapel


ancient technique, new approach



Masaccio probably had several hours (at most a day's work, in any case), to paint this head of Saint Peter in the Brancacci Chapel of Santa Maria del Carmine in Florence. Note the fine crack running around his neck, the top of his tunic and the edge of his yellow mantle: this crack is the edge of the giornata, the area of wet plaster that apprentices would have prepared for the master painter to cover in one day. Is it not extraordinary that, presumably without major alterations, this beautiful, expressive face was painted rapidly, and under pressure?

Olive Oil 2

Fruit of the Month: the Olive
or
The Olive Harvest 2013


Recently (January 2014) a horrifying animated chart appeared in the New York Times exposing (not for the first time) olive oil fraud. This should make us appreciate the small producers more and understand that their prices are high for a good reason. And here is an excellent blog by Tom Mueller which covers the subject of olive oil and oil fraud very well.
For more on olive oil please see last year's post as well.
 

I was unable to participate in the olive harvest this year as planned, but a friend who took part for the first time has provided some photos and a couple of excellent short films to give an idea of how things are done nowadays in Chianti.

This year rain was a problem: it held up the harvest from one day to the next. But in the end everyone managed to make their oil.

Every Bed of Roses has its Thorns



The Other Side of the Idyll



Writing this blog I sometimes worry that we only ever talk about the Good Things of life in Chianti. Although the intention is to describe the best of what's available, be it food, culture, craftsmanship or festivals, or the most interesting aspects of our garden, the seasonal changes etc., we run the risk of giving the wrong impression. Although I doubt anyone truly believes we are living in some sort of enchanted bubble.

Conversation with an Historian of Tuscan Architecture

Scattered Notes on the Past


View of Florence, Raffaello Arcangelo Salimbeni (1914-1991)
Just the other day we had a visit from an architectural historian, a retired professor from Florence University who specialises in Tuscan architecture, from the grand to the humble. Obviously we hoped to glean something more about the history of Le Ripe, but although he could give us no greater indications than the name of the archives (in Florence) where we should carry out further research, his conversation was full of fascinating snippets which I thought to compile in a post for those who might be interested. (If I repeat things already written in other posts I apologise to our most attentive readers!)

Mille Miglia Vintage Cars

The Mille Miglia Thousand Miles Rally 
May 2013

Mille Miglia poster: "the most beautiful race in the world"

It has been a cold and rainy May this year, the wettest in 200 years people are fond of telling you, with astonishment and dismay. But for the Tuscan sector of the Mille Miglia this year the sun emerged, the rain stopped falling and blustery clouds raced over clean blue skies for the duration. We had other commitments, but managed to see a part of the rally from a stretch of the SS2 (the ancient Roman Cassia) between Tavarnelle and San Casciano in Val di Pesa. The rally stopped for lunch in San Casciano again this year, so the lucky sightseers and car enthusiasts who converged there were treated to a long and considered inspection of the 400 odd (and some are truly odd) cars parked in the main square while the drivers dined.

A new perspective on Siena Cathedral

Heaven's Gates
La Porta del Cielo

Duomo of Siena seen from the west: the tour takes in the portico around the cupola


Since April 2013, Siena Cathedral has opened its attics to the public. Never seen before except by those who built the cathedral from the 13th century on, the attics have now been fully restored and secured. Damaged over the centuries by fire, earthquakes, wars, humidity and even termites, the underside of the roof of the cathedral was in dire need of attention. These 'attics' have been carefully restored and converted into passageways and lookout points for stunning views both inside the cathedral and of its extraordinary artwork, as well as of the panorama of Siena and beyond, seen from narrow balconies and terraces that work their way around the cathedral's heights.

The guided tour begins near the cathedral's font. A small crowd of  tourists, young and old, briskly climbs a narrow, spiral staircase in white marble whose small arched windows let in light through yellow alabaster panes.

Local Artisans

 Master Craftsmen
i Mastri Artigiani


The master's hand. It's everywhere: in the shape and style of the chimneys; in the 'ricciolo' or curl finishing an iron rod; the precision of a turned edge; the dressing of a block of stone; the dovetail joint in a drawer; the severe yet stylish cut of a door; the line and curve of a banister; the pattern in which floor tiles are laid; the contrast between the wall colour and its fine line of bordering; the panels of colour under a railing or beneath the ceiling; the careful choice of stone or brick or wood to frame a door or a window; the perfect arch...a tutto sesto (Roman arch) or ribassato or ellittico; the coupling of stone and terracotta; the silent, smooth slide of a drawer...

Le Ripe History

il podere Le Ripe
- Le Ripe the farm -
a brief history

Le Ripe photographed from beside the river Pesa, July 1946 - note two haystacks, one of wheat and one probably of oats

The old farm buildings and property called Le Ripe lie just within the Castellina commune, cheek to jowl with the Radda commune (all our neighbours are in Radda) in the province of Siena, right at the border with the province of Florence, very near Panzano in Chianti, in the commune of Greve in Chianti. Over the centuries Le Ripe and its inhabitants would inevitably have been caught up in conflicts large and small as those borders were contested, shifting back and forth.

The farmhouse, barn and concimaia or midden were most likely built several hundred years ago by tenant farmers (mezzadri) who needed to make the best use of the land allotted them: they didn't waste the flatter land on buildings, it was needed for crops.

Water

Water VI


three sets of guttering on one roof
During our renovations we planned to direct all the rainwater from our (extensive) rooftops and possibly from the threshing floor as well, into a large water tank. This water would then be used for the garden and vegie patch. The system is ready but the tank has not been installed yet.

Water

Water V



The water from our well is pumped into two cold water tanks, one of 750 litres, the other 1000 litres. In the first case (in the cottage we call the Fienile), it is either used cold or heated via a conventional gas-fired boiler which connects to taps and standard radiators. In the other, it is either pumped straight up to the house for drinking, washing and cooking, or transferred to another, insulated 1500 litre tank and heated thanks to a modern wood-fired furnace. The furnace heats the upper layer of water and the solar thermal panels' fluid heats the lower layer through a heat exchanger. 

This second hot water tank is also called a 'puffer' and hot water is accumulated from the bottom up, according to rising temperatures, ('stratification'). In the upper layer there is a separate sub-tank storing the hot water for washing. The warm water for the underfloor heating is stored in the surrounding volume. Hot and cold water is then pumped into the apartments. The water for heating runs through hundreds of metres of flexible tubing which spirals beneath the floors.
