Midnight on Halloween is the witching hour! Throughout history, the myth of the witch has been a tool of oppression, empowerment, and an expression of all things wyrd and wonderful. But do you know these famous witches? Scroll on to test your knowledge...

We’ll kick off with some of the best known witches of all time. Depicted in numerous images, and portrayed on stage thousands of times, this coven of three contains some of the most infamous sorcerers around.

The fact there’s three of them is one of your biggest clues. If you still need a hint, take a closer look at what they’re throwing into the cauldron…… 'Eye of newt and toe of frog, Wool of bat and tongue of dog'. Have you worked it out yet?

The three witches play a pivotal role in Shakespeare’s Macbeth. Used to represent evil, darkness, chaos and conflict, their presence in the opening scene gets the play off to a very ominous start. 

Our next witch has a very different image. Although she famously called on the dark arts and used her powers against men on various occasions, she also has a number of redeeming features. 

This famous witch is best known for turning her enemies into animals. Most of her adversaries ended up as swine, although some were transformed into monsters, birds and sea creatures. 

Descriptions of this witch and her extensive powers date back thousands of years. Among the many literary works she appears in are Homer’s Odyssey, Virgil’s Aeneid, and Ovid’s Metamorphoses. So do you know which ancient sorcerer we’re talking about?

Arguably the most famous which from classical myth and literature, Circe was the daughter of the sun god Helios and the sea nymph Perse (some sources also list her as the daughter of Hecate and Aeetes). Thanks to her impressive powers, long life and  multiple cameos, Circe remains one of the most famous, and feared, witches of all time. 

Our next contender isn’t a witch but a wizard. Over the years, male sorcerers have generally been treated more kindly than their female counterparts, and this wizard is no exception. Rather than being a recluse or a bad omen, he’s often painted as an enchanter and a wise man.

A loyal companion to one of England’s most legendary kings, this witch was known for his ability to appear and disappear without warning, control the climate and change shape. He was also considered a profit and a wise man. Do you know which famous witch we're talking about?

Merlin is a fixture in many of the most famous Arthurian legends. He first appears in Geoffrey of Monmouth’s History of the Kings of Britain (1136 CE) where he’s depicted as a precocious youth. He also appears in Sir Thomas Malory's Le Morte D'Arthur (1469 CE) and Merlin by Robert de Boron (12th century CE).

These photographs were taken by Julia Margaret Cameron in order to illustrate Alfred, Lord Tennyson’s recasting of the Arthurian legend. In the images, Merlin is portrayed by Henry Hay Cameron, the photographer’s husband.

Once a famous piece of art has cemented itself in history, it can be hard to imagine that the work started as nothing but an idea. Artists often prepare sketches, models, or drafts before the ultimate work. Scroll to compare conceptual drawings with the final product.

Far from the ornately gilded finished piece, this pencil drawing of The Kiss shows the remarkable simplicity behind one of Klimt's most acclaimed works.

The finished painting, appearing courtesy of the Belvedere in Vienna, was created at the peak of Klimt's 'Golden Period' around 1908. Scroll back and forth to compare the early draft with this one!

This sketch, which appears in a letter to Paul Gauguin, is one of the earliest iterations of van Gogh's portrayal of his bedroom at The Yellow House in Arles, France. The artist produced multiple versions of the piece between 1888 and 1889.

This version, the third and final painting of his bedroom, is currently on display at the Musée d’Orsay, Paris. In addition to subtle differences in color, this version is somewhat smaller than the others, and features updated artwork on the walls.

In 2007, Korean artist Nam Kyung-min created this gargantuan oil painting inspired by The Bedroom. In a nod to van Gogh's decorations, she's recreated several of his other artworks around the room. See if you can identify them all!

Danish sculptor Bertel Thorvaldsen produced this series of sketches to prepare to sculpt the mythical lovers. All the poses tell the story of the intimacy, but only one became set in stone. See if you can guess which drawing turned into the completed piece!

The lovers are on display now in Thorvaldsens Museum in Denmark. Thorvaldsen completed the piece in the first decade of the 1800s. Contrast this lifelike masterpiece with the unembellished drawings which preceded it. 

This illustration of Cupid and Psyche intertwined and facing forward went on to be the model for the ultimate sculpture. Is this the sketch you guessed?

For a change of pace, first look at this unrestrained sketch by Frank Gehry, then try to guess what the final product is. Hint: It is much larger in scale than the other works.

Did you guess that it became the Walt Disney Concert Hall in Los Angeles, California? The venue was conceptualized in 1987, but wasn't open until 2003! Below, you can click to examine the building in 360º using Street View.

Kara Walker's 2014 installation A Subtlety was powerful, poingant, and remarkable in its scope. But even it began as a series of simple sketches.

The installation took place in a disused sugar factory in Brooklyn, New York. The enormous sphinx at the center was encircled by smaller but equally powerful pieces. Watch the video below to see the artist discuss the exhibit and learn how it was created.

Welcome to Coconino National Forest in Arizona, USA. From up top of the O'Leary Peak Lookout Tower, you can see across miles of this beautiful, natural landscape, from dry deserts to verdant forests.

Start your trip off by walking the Lava Flow Trail, at the base of Sunset Crater Volcano, near Flagstaff. This flat walk is barely a mile long, the perfect introduction to the plants and geology of this National Forest.

This moderate, 8.8 mile hike is accessible all year round, and dog-friendly,making it popular with many of the forest's visitors. Keep an eye open for maidenhair ferns, scarlet penstemons, and cottonwoods.

This dormant volcano is the highest point in the whole of Arizona. You can start your hike at the Arizona Snowball ski resort, from here, walk 4.8 miles along the Humphreys Summit Trail to the peak.

An oasis in the desert, this popular swimming hole, known as 'The Crack', attracts crowds of day trippers. Why not take a break here, lounge on the smooth rocks or plunge into the cool waters. We'll catch up later.

Cathedral Rock has to be one of the most photographed sights in Arizona, and a landmark on the Sedona skyline. It's a tough climb up to the rock formation, located in Yavapai County, about a mile west of Arizona Route 179.

Before the forest existed, the area was home to many groups of Native Americans. The Palatki Heritage Site comprises a number of ancient cliff-dwellings, carved by the Sinagua people of the Ancestral Puebloans into the red sandstone around 800 years ago.

Association Football (known as 'football' or 'soccer') is the world's most popular sport, watched and played by countless millions around the globe. But how well do you know its history? Scroll on to put your soccer knowledge to the test.

Time for kick-off. In what year was the sport of Association Football officially invented?

Forms of soccer were played long, long before it was codified as a sport, but the first official rules were written at the Freemasons’ Tavern in Blackheath, England, 1863. Some of these rules still exist but many have been heavily modified or removed over the years.

Spot quiz: in what year were penalty kicks first added to the rules of the game?

A penalty kick is when an attacking side is awarded a free shot at goal from a marked distance (these days 12 yards) if a foul is committed by the defending team in the penalty area. They were originally called ‘kicks of death’. It’s shame that name didn’t catch on!

Soccer is now the world's most popular sport, but when and where was the first World Cup tournament held?

These days the World Cup is one of the world’s great sporting occasions. Every national team enters and plays through a system of qualifying rounds to reach the final tournament, held every four years in a different host nation. Uruguay hosted, and won, the first. 

The referee's whistle blows! When was the dreaded Red Card first introduced to the game?

Players can be sent from the field for committing a variety of offences, such as dangerous play, preventing a goal-scoring opportunity, or accumulating two yellow cards for less serious offences. The ref will show a Red Card to the offending player.

These days international football has a busy calendar with the World Cup and individual continental tournaments, but the idea didn't take off immediately. Can you name the year the first ever international football match was played and by which two nations?

These two still contest a very heated rivalry!
