In the midst of London, carefully hidden from the eyes of Muggles, are the buildings and offices of the Ministry of Magic. One of the most important buildings there, not far from Parliament, is the Great Wizarding Library. Outside the Library are statues of the four Hogwarts founders (Godric Gryffindor, Helga Hufflepuff, Rowena Ravenclaw, and Salazar Slytherin). Each statue is made of a different material (bronze, stone, marble, and steel).

Can you figure out the order of the statues, from left to right, and which material each statue is made of?

1. The stone statue is somewhere to the right of the statue of Godric Gryffindor.
   
   
2. The marble statue is somewhere to the right of the statue of Rowena Ravenclaw.
   
   
3. The statue on the far right is neither the statue of Salazar Slytherin nor the stone statue.
   
   
4. The statue made of steel is somewhere to the left of the statue of Godric Gryffindor.
