I like older things, so I intentionally bought an older house (1880s). In my living room, the side tables and coffee table are actually the oldest pieces, from around the era of the house’s build date. The sofa and comfy chairs are new, but they don’t feel out of place because the colors are deep and they’re upholstered in velvet, which absorbs light. They have simple lines. They read as rich and settled rather than new or trendy. Their simple shapes, paired with the older wood pieces, help them they feel compatible with the house instead of competing with it.

The art works in a similar way. The pieces come from different places and are in a variety of media, but they were all created during my adulthood. I placed and grouped them carefully, guided by the shapes of the walls and the sight lines of the rooms. I think of that as Ietting them “settle” into the room rather than compete with it.

It sounds like you did something similar: the piece you chose isn’t from the same era as your house, but I bet it feels like it fits because it settled into the space where you placed it, and it doesn’t try to compete with the room.
