If one thing sums up the 21st century it's got to be all these default profile pictures.
You've seen them literally thousands of times, but they're completely generic and interchangeable.
Future historians will use them to symbolise our current era, and here's why...
To understand what any society truly believed, and how they felt about humankind, you need to look at what they created rather than what they said.
Just as actions instead of words reveal who a person really is, art always tells you what a society was actually like.
And this is particularly true of how they depicted human beings — how we portray ourselves.
That the Pharaohs were of supreme power, and were worshipped as gods far above ordinary people, is made obvious by the sheer size and abundance of the statues made in their name:
It's over 500 years old and the perfect example of a strange architectural style known as "Brick Gothic".
But, more importantly, it's a lesson in how imagination can transform the way our world looks...
Vilnius has one of the world's best-preserved Medieval old towns.
It's a UNESCO World Heritage Site, filled with winding streets and architectural gems from across the ages.
A testament to the wealth, grandeur, and sophistication of the Polish-Lithuanian Commonwealth.
Among its many treasures is the Church of St Anne, built from 1495 to 1500 under the Duke of Lithuania and (later) King of Poland, Alexander I Jagiellon.
It's not particularly big — a single nave without aisles — but St Anne's makes up for size with its fantastical brickwork.

To celebrate, here are the 10 best things I've written about Spain: from why Barcelona looks the way it does to one of the world's most underrated modern architects, from the truth about Pablo Picasso to the origins of the Spanish football badge...
What makes Barcelona such a beautiful city? It wasn't an accident — this is the story of how the modern, beloved Barcelona was consciously created:
When Vincent van Gogh started painting he didn't use any bright colours — so what happened?
It isn't just about art.
This is a story about how we're all changed by the things we consume, the places we go, and the people we choose to spend time with...
The year is 1881.
A 27 year old former teacher and missionary from the Netherlands called Vincent van Gogh decides to try and become a full-time artist, after being encouraged by his brother Theo.
What does he paint? The peasants of the countryside where his parents lived.
Vincent van Gogh's early work is unrecognisably different from the vibrant painter now beloved around the world.
Why?
Many reasons, though one of the most important is that he had been influenced by his cousin, the Realist painter Anton Mauve, who painted like this:
He rose from obscurity, joined a revolution, became an emperor, tried to conquer Europe, failed, spent his last days in exile — and changed the world forever.
This is the life of Napoleon, told in 19 paintings:
1. Bonaparte at the Pont d'Arcole by Antoine-Jean Gros (1796)
Napoleon's life during the French Revolution was complicated, but by the age of 24 he was already a General.
Here, aged just 27, he led the armies of the French Republic to victory in Italy — his star was rising.
2. The Battle of the Pyramids by François-Louis-Joseph Watteau (1799)
Two years later Napoleon oversaw the invasion of Egypt as part of an attempt to undermine British trade.
At the Battle of the Pyramids he led the French to a crushing victory over the Ottomans and Mamluks.
