Pick up the crown.
The room fills with gas.
Run towards the door quickly and dive underneath to reach the next chamber.

Now we have a nice riddle to solve.
We have got four doors with markings. Take a close look at them.


     

Now go towards the lever and use it to bring up a Taurus from the flames.
Place the crown on it's head.
A couple of levers will appear in the room.
We will start with the Taurus.
Don't ask me why I chose that, mainly because the crown thing was a hint.
With up and down you can navigate within the clock.

First level is the zodiac sign. Pick Taurus by pressing left or right.
Press down to reach the next level sun. Pick the number 2 (II). The sun is underneath the number 2 on the picture.
Press down to reach moon. Pick 4 (IV)

Voila, the door opens.
Step through.
