ARCHAEOLOGY

Lost Spanish temple reveals scientific secrets

A mysterious cave-temple built by the original inhabitants of the Spanish Island of Gran Canaria contains evidence of their advanced knowledge of astronomy, a Spanish archaeologist believes.

Archaeologist Julio Cuenca, who has been studying the area since the 1990s, believes the site is the only one of its kind in the world.

"It's like a projector of images from a vanished culture," Cuenca told Spanish national news agency Efe, referring to the Guanches, or aboriginal inhabitants of Spain's Canary Islands.

Guanches are thought to have migrated to the island chain some 3,000 years ago, but their culture began to disappear when Spain conquered the islands in the 15th century.

But Cuenca's study of the cave in the aboriginal region of Artevigua adds to the knowledge of their fascinating culture. 

Light from the rising sun enters the cave's  5-metre high dome room, from the spring equinox onwards, and is visible inside for about two hours every day from March to September.

It is projected onto the walls in a series of fertility images which change with the seasons.

Male phallic images appear on top of carved triangles, thought to represent the female pubic area. These images gradually shift to reveal a pregnant woman and then a seed. 

Cuenca has recorded the summer solstice inside the cave and also observed that moonlight created an image on the wall during the winter solstice.The sunlight also marks the points of solstices and equinoxes.

The local archaeologist has made a career from studying the settlements of the earliest inhabitants of the Canary Islands.

The names they gave to locations on the islands were wiped from maps in the 18th century when the Catholic Church Hispanicized the names of the local topography.

Cuenca described the astronomical knowledge necessary to design the Artevigua temple as "impressive" and more advanced than that seen in any of the other 21 caves which have been found in the area.

He noted that the discovery would lead to a reassessment of how people thought of the so-called "primitive" former inhabitants.

A webcam is being installed in the temple to allow the public to view the sunlight projections live via the internet.

HISTORY

Why Spain is still in the wrong time zone because of Hitler

As Spain again prepares to put the clocks forward on Saturday night, we look at the fascinating reasons why the country has been in the wrong time zone for the last 75 years, the possible effects of this historical blip on Spanish society, and why there's still no sign of it changing.

Why is Spain in the wrong time zone?

Madrid lies directly south of London. Spain is geographically in line with the UK and Portugal. It makes sense, then, that Spain was in the Greenwich Mean Time (GMT) zone until around 75 years ago.

But that all changed in 1940. With Nazi Germany occupying Belgium, Holland, and recently invading France, Spain’s own facist dictator, Francisco Franco, travelled to the French border to meet with Hitler, the man he and many other believed would go on to dominate Europe.

The momentum was clearly with the Nazis, at the time, and Italy had already pledged its support to Hitler. Although he wanted the same from Spain, Franco, however, didn’t have much to offer. With the country ravaged by its own recent Civil War – in which Franco’s victory was heavily supported by Hitler –  Franco felt obliged to make a gesture of some sort.

Although ultimately remaining neutral in the war, Franco decided to show his support for Hitler by agreeing to put Spain’s clocks forward by an hour in an act of solidarity with Nazi Germany. 

Spain has remained in the Central European Time zone ever since, in line with countries as far east as Poland. That means that Madrid currently has the same time as Warsaw in Poland 2,290km away but is one hour ahead of Lisbon which is only 502 km away. 

The consequences of Spain being in the wrong time zone

But Franco’s decision all those years ago isn’t just a quirk of Spanish history, or testament to the extent to which the legacy of that period still looms over Spanish society, it was a decision that, experts say, has had a lasting impact on Spanish culture and society that underpins everything from Spaniard’s sleep cycles and meal times to the country’s birth rates and economic growth.

In recent years there have been calls to make the switch back to GMT because many believe the time zone quirk is affecting Spaniard’s productivity and quality of life. In 2013 a Spanish national commission concluded that Spaniards sleep almost an hour less than the European average, and that this led to increased stress, concentration problems, both at school and work, and workplace accidents.

Some experts believe this explains the Spanish dependence on siestas – that is, that the lack of sleep makes them necessary – but in reality the siesta has been a consistent feature of Spanish life for centuries for many of the same reasons it still is today: in southern Spain, the fierce summer temperatures make it necessary to stay at home during the afternoon.

One effect of the siesta however is that the break in the day means Spaniards work the most hours in Europe yet at one of the continent’s lowest levels of productivity. A lack of sleep contributes to siesta taking which, in turn, means Spaniards work later into the evening and could partly explain Spain’s notoriously nocturnal lifestyles and late meal times. 

Despite the country running on CET, Spaniards’ eating patterns roughly mirror GMT. Many Spaniards eat lunch at what would be 1 or 1.30pm in London (the traditional 2 or 2.30pm in Spain) and dinner at a reasonable 8pm in London (but 9pm or even 10pm as is customary in many parts of Spain).

Making the change and returning to GMT would, according to Nuria Chinchilla, professor at Spain’s IESE business school, help Spaniards “return to the natural order of our circadian rhythm (our 24-hour physiological cycle) that goes with the sun… and the sun in Greenwich, not Germany”.

“If we don’t (change to GMT) we lengthen the day, eat very late and then don’t sleep,” she added.

Why hasn’t Spain moved to the right time zone yet?

The debate about which time zone Spain belongs in was reinvigorated following recent proposals at the EU level to scrap entirely the daylight savings custom. 

In 2018 the EU Commission announced a proposal to abolish the custom after polling showed that 80 percent of Europeans are in favour of staying permanently on summer time.This debate naturally had many in Spain wondering about whether they were in the right time zone.

But owing to a combination of the COVID-19 pandemic, Brexit, and various other bureaucratic difficulties, the proposal was shelved. Member states cannot decide unilaterally on the question of daylight savings, but they can decide which timezone they want to be in. 

Spain has had various commissions over the years exploring the impact of daylight savings and timezones, but no concrete proposals over a return to GMT have ever been made, despite the benefits experts claim it could bring.

Although the government’s focus has been drawn by more pressing issues in recent years – and the issue of time and daylight savings shelved at the European level – expect discussion of whether Spain is actually even in the right time zone this weekend when the clocks do go back, or if the linked issue of daylight savings is eventually taken off the shelf at the European level.
