In reply to Simon4:

Yes we descended the Lion the way we'd come. Logistically this is easier because you can base yourself in Cervinia and don't have problems getting back to your starting point.
I wouldn't say descending was any more serious or harder than the climb up other than you're more tired but then its not dark for some of it (hopefully!).
In descent you can abseil the Echelle Jordan and Corde Tyndall, otherwise you move together placing gear as you did in ascent.
We, and the other parties that day, took about the same time in ascent as descent so its not an "easy" descent, but not serious either, essentially you repeat the climb. We also spent both the night before and after the climb in the Carrel Hut as everybody else did, you'd have to be quite fast to get all the way down the same day.
Of course getting to the Carrel is a climb in its own right.
