In the 1930’s Xavier Guichard, a Frenchman, thought he had discovered the proof that Bronze Age people were already familiar with longitudinal and latitudinal lines (meridians and parallels) as we use today, implying that they already divided the circle into 360 equal parts. It also implied, of course, that they knew about the Earth circumference. A number of towns, villages and hamlets, all bearing names apparently derived from Alesia appear to be located on these lines, as markers of this geometry. Because the name reminded him of the Greek term Hal meaning ‘salt,’ Guichard dubbed these lines ‘Salt Lines.’

Unfortunately for him, Guichard was slightly wrong. Salt Lines ran slightly closer to one another that they should have in a 360-degree geometry. Sixty years later only was Alan Butler able to determine what the problem was with Guichard’s lines. The ancient system Guichard had discovered worked on a 366-degree circle, nor 360. Clearly speaking, the globe was divided into 366 equally-spaced meridians, not 360, which explained why the lines were too close to one another.

When I first heard about what looked like a ludicrous theory, I was quite sceptical. And yet I was convinced Alan was right about the rest   so why not about Salt Lines? I set about verifying this daring hypothesis, checking the geographic coordinates, not only of villages and towns seemingly derived from Alesia, but also great cities and capitals of antiquity at the same time. Backing my work with probability calculations, I soon found out that, improbable thought it might seem, these lines had indeed existed. I traced them not only in Europe, but also on four different continents as well – in Asia, Africa, Central America and South America. I was stunned and electrified by such an unexpected result. Salt Lines, no doubt about it, had been surveyed almost all over the globe by an ancient civilisation. And the birth of the world’s first great civilisations – Sumer, Egypt, the Indus Valley, Greece, the Olmecs in Mesoamerica and the pyramids of Caral in South America all bore the fingerprint of a single geometrical system.

Let’s sum things up. Salt Lines were of two kinds:

• Latitudinal Salt Lines (or Salt Parallels), deriving from the equator and running in an east-west direction: from the North pole down to the South pole, and then continuing on the other side of the planet back up to the North pole, we cross 366 parallel lines in all.
  
  
• Longitudinal Salt Lines (or Salt Meridians), the origin (‘Greenwich’) of which was yet to be discovered, were running in a north-south direction: there were 366 of them.
  

The capitals and great sanctuaries of the world’s first great civilisations were located on the Salt Lines. My research also showed that the river Jordan in the Middle East, that Alan had told me was running along a Salt Line, could well have been the Salt Lines Prime Meridian, the ‘Greenwich’ of Megalithic times. The Jordan Valley is literally packed out with Megalithic stone circles. To cut a long story short, mathematics, archaeology as well as chronology were all suggesting this sacred river had been the Salt Lines Prime Meridian.

Mi investigation finally led me to the precise discovery of Alesia, which, according to classical Greek historian Diodorus Siculus, was ‘the hearth and mother-city of all Celtica.’ And it’s not one but three great Alesias that I found, each one perfectly aligned on a Salt Line running exactly 32 Megalithic degrees from the Jordan (the central Alesia rising precisely at the midpoint between the other two!). The central Alesia – which is not the place where mainstream archaeology claims Caesar once defeated Gaulish leader Vercingetorix – is located near the Burgundian village of Guillon, France. In this place the late Bernard Fèvre, another researcher of the 1980’s and 1990’s, had been fighting with academics for two decades to try to prove Guillon was the real place of the lost city.

This is how, knowing all that, I decided to share my discoveries in a book called Les Lignes d’or (‘The Golden Lines’), which refers to these incredible Salt Lines and the immense knowledge that is attached to them.
