Unreachable item (?) in Old Akelarre

I'm pretty far into the game (but haven't triggered NG+), and on a whim I walked back from Majula to Old Akelarre, and inside the first oval-shaped room, where the 6 goblins ambush you, I can see, up on the second level, to the left as you enter the room, a glowing spinning thing. It looks much the way things look when another player character drops something for you to pick up.

I can't find any reference to this item anywhere, much less any way to get up there to get it. Has anybody else seen this, and has anybody gotten it? I need it. It taunts me.

EDIT: Screenshot of the item in question

Solution 1:

This item is a little tricky to get to. You have to do a running jump off the stairs to get to it.

It might take a few tries, but it's as straightforward as it sounds. Run up the stairs, then turn 90 degrees toward the shelf, and jump.

After doing a bit more research, there is nothing more in the first room, other than what you can find in the ground floor. Whatever it is you're seeing, it's not an item.
