Don't you hate it when you get stuck in a game before Leon has had a chance to finish a walkthrough! ;D

Drained the fountain of water and read the markings except the one the sylph is sleeping on. I have got the decoder, sceptre, water in the vial from the pool in front of the mirror, On/off switch thing, magnifying glass, makeup and scroll.
How do I wake up the sleeping sylph (on/off switch only does so temporarily) and/or what do I do next?

You need to do two things so that the sylph will go away.
Basically, the sleeping sylph is a female. Therefore, she probably cares about how she looks. So you need to:
a. Make sure she doesn't look good (makeup).
b. Make sure that she will see her reflection when she wakes up (water fountain).
Thanks very much.
I could have sworn I'd already tried using the

on her already. Oh well :P
