There’s a sound that 
reverberates through Skyros town during the ‘Apokries’ Carnival season 
that you will never forget. 
It clangs and rumbles and bounces by, hiding in the side streets before emerging again, louder, as if its force has doubled. It’s an echoing chime that makes you either stop in your tracks or inquisitively follow…
   
  
 
For weeks, these figures can be seen strolling the streets and piercing the still air with the clatter as soon as evening sets in. But on the last weekend before what is known as ‘Clean Monday’ (‘Ash Monday’ or the first day of Lent), the Carnival becomes a true spectacle.

In the weeks leading up to the 40-day 
fasting period before the Greek Orthodox Easter, parts of the country 
come alive with grand celebrations. I never thought of Greece as being 
associated with carnivals – perhaps because of the many years spent on 
islands where the atmosphere was serene and mass gatherings more 
intimate – yet there is great significance in them.
While Athens is awash with street 
parties and late-night reveling, some of the mainland towns put on quite
 a show, including the ‘Flour War’ in Galaxidi and the grand parade in 
the port city of Patras. The Sporades island of Skyros is no exception 
to the rule of continuing age-old tradition during this time. In fact, 
it has one of the most unique.
Here, masquerade and merriment stem from
 the folklore of the ‘geros’ and ‘korela’. Men play the role of the 
‘geros’ and wear a furry black cape, white trousers, waist belt of goat 
bells (weighing in at around 50 kilos) and a hanging goatskin to cover 
their faces. Jumping around and waving their wooden sticks, they are 
accompanied by the veiled ‘korela’ – the island girls or Skyrian brides –
 dressed in white and yellow waving a scarf to lead the way (some men 
dress this part too).
This spectacle is unlike any carnival 
I’ve ever witnessed. It captures your attention by startling you with 
its cacophony, and by the awe as you question the meaning. This 
celebration is not only about the coming of Lent but about the end of 
winter and the start of spring, as well as the mythological tales of a 
young Achilles who used Skyros as his hiding place to avoid being 
dragged into the Trojan war, where he was disguised as a girl. Skyros, 
it seems, has a long history of clever disguise.

Starting from the castle at the very top
 of the hill in the early evening on the Saturday, dozens of these 
traditional figures paraded down through the main street that winds 
through the quiet neighbourhoods of Skyros town. The town was heaving 
with people awaiting the final performance, filling bars and 
restaurants, pavements and balconies. Rather than wait at the bottom, I 
decided to join the mix of quirky, masked characters and become a part 
of the convoy, whose aim was to make as much noise as possible as it 
entered the last stretch of town, to gather in the open square to dance.
The side streets form the backstage of 
the Carnival, where veils of costumed locals briefly come off as they 
take a rest from the hard work of the performance. The majority of these
 guys continue until the early hours of the morning, so the switch of 
commotion to calm is necessary, and builds excitement in the crowd 
awaiting their reappearance.
And while the goat men are laid to rest 
for another year, the playfulness continues until the final day when 
satirical performances known as the ‘Trata’ take place. These comical 
performances poke fun at topical issues, society, the island’s Mayor and
 innocent bystanders. Even if you don’t understand, it’s fun to join the
 energetic crowds, sip alcohol from the cups hanging around their necks 
and rejoice with them in what is undoubtedly one of the happiest times 
of the year.
