Relief Panels Tangent

In our last Relief Panels installment (9/25/08), I'd become captivated by that decorative element centered between the two windows (top image), beneath the Anthemion scroll. (Anthos is Greek for flower.) Familiar it was, but where had I seen it and how to describe?

For starters, it's geometric and composed of straight line segments.

All of its angles, both interior and exterior, are right angles, and as such it's a parallelogram. (If only I could do geometry over, I'd ace it!)

A similarly shallow--or low--relief panel--or the effect thereof (image second from the top), conjured by the application of a small bead, in a manner that abstractly suggests a frame. Close but no cigar.

I was reminded of the returns in Greek Fret work, geometric patterns formed of short fillets, bands, or reglets, variously intersecting in rectangular containments.

This band embellishes a cottage in Pico-Union, for many years a dentist's office. A classic example of a Greek Fret, or the Greek Key design.

Perhaps I'd seen the pattern in furniture? I consulted Joseph Aronson's The Encyclopedia of Furniture. The illustration provided a momentary balm.

The Girl Next Door. A near match (see bottom image) occurs in chummy Kinney Heights, on a block I regularly walk. How could the connection have eluded me so, and might I have also seen the pattern elsewhere?
