Thanks for the suggestion on the sculpture, lefty.
In theory, yes, I could suspend the sculpture, but I don't know if that's the best way to display it. It was meant to be viewed as a totem; e.g. vertically and looking up at it. The face of Christ is particularly compelling, but loses something when viewed from the "wrong" angle.
Because it is so tall, there are only 2 rooms in the house that can accommodate it: the bedroom and the main living room. Rather than suspend it, per se, I have considered putting it in a corner of the living room, but given that the balcony runs around 360 degrees of the room, and is lower than 12 feet in height, it would have to sit out into the room a little bit. Which is problematic, as there is some kind of entryway in three corners of the room. I really like the bedroom idea, as a Christ figure doesn't really bother me there, but if not I think the best idea is in the far left corner of the room in this photo:

nestled up against the balcony bannister, facing out towards the room, and perhaps up on some kind of pedestal just to give it a little extra height. This would also allow you to view it up close from the balcony.
But that means it is out into the room a good bit, which is a bit problematic from a furniture arrangement standpoint, but is otherwise fairly compelling and dramatic. We'll just have to see.
As for the other three totems still attached to the house: Two are hardwood and are doing just fine outside. They have been treated with an oil-based stain to protect them, and they are in very good shape, aside from the one having fallen down - due more to its lashing than its own condition. But this one that was separated and a small one on the back were made of poplar, and the weather and the insects are just having their way with them. So that back one I have considered also bringing inside (it is only about 4 or 5 feet tall and could be displayed more easily indoors). If I were to do so, I'd try to take some kind of plaster mold of it and replace it outside.
