In the course of a lifetime, each of us accumulates countless images: visual impressions laid up in the storehouse of memory. Unlike jewels and precious metals, these treasures do change with time; they corrode, distort, melt, collide with each other, fuse, and give birth to other images. Imagination contributes its share, combining, changing, and exchanging images by design and accident both.
There is also loss beyond imagining: countless memories lost forever, or merged, or faded, or exchanged one for another. Yet loss only increases the richness of remembered images.
