Besides being a remarkable work of art from the Chola dynasty, it is also a fascinating optical illusion – and one of the earliest known examples.
And according to the folklore surrounding the temple, the puzzle can also reveal the personality traits of the viewer.
The challenge is to see both animals in the photo sharing one head.
And you only have seven seconds to complete the puzzle.
So buckle up, set your timers and test your puzzle-solving skills.
Optical illusions are images designed to trick our minds and can be a simple IQ test.
They test our understanding of reality, depth and perspective as we try to make sense of what lies ahead.
The benefits of optical illusions
RESEARCHERS have developed many tests that show how different brain regions respond to optical illusions.
Not only are they entertaining, but they also shed light on how our brains interpret visual data.
By regularly exercising your brain a little, you increase your ability to focus and observe details.
Studies have shown that people who regularly challenge themselves with optical illusions and puzzles see great improvements in their problem-solving skills, concentration and attention.
Improved concentration and attention span can, in turn, help prevent cognitive decline in old age.
Psychologists from the University of Glasgow discovered that staring at an optical illusion can improve vision by allowing you to see small print.
And this puzzle is sure to test your attention and intelligence as you try to spot both animals.
But before you take on this challenge, see if you can do it first look for the brazen ghost trying to blend in within this party scene in super fast time.
If you can, you will have the watchful eyes of a clever mind, but beware: they are very good at keeping secrets.
You can also try and find all five differences between the two identical images.
Or get started finding the sausage that should definitely not be included with fruit and vegetables.
Returning to the challenge: were you able to solve it?
If you haven't seen it, check it out again.
Still no luck? Don't worry, we've got you covered.
The stone carving depicts an elephant and a bull that appear to share the same head – and there's a unique way to spot them both.
If you cover the body of the creature on the left, the animal on the right appears to be an elephant.
But if you focus on the left beast, it looks like a bull with its head towards the sky.
However, you can't see them both at the same time – and that's exactly how the sculptors intended it almost a millennium ago.
Seeing the bull first apparently means you are stubborn and fierce.
You know how to stay strong and positive in times when it seems impossible.
If you see the elephant first, it means that you are loyal and respectful to your friends and family.
You are thoughtful and considerate and treat people with kindness and respect.
Cheers if you managed to solve this bizarre challenge in less than seven seconds: you are a genius with perfect 20/20 vision.
