This rectangular 'four square' pattern is all over the place, I tried calling them quatrifoils recently, and they were posted some time back in E. Velinska's blog. They were frequently one of the patterns used as backgrounds in some earlier (than VMs) French manuscripts. They were still used in the C-14 years.
See thread "Wallpaper patterns". [Nobody got excited about it then.]
I hadn't heard them called diapers, but diapering is a heraldic term referring to a type of patternation.
The VMs has several varieties of this pattern, a partial four way division of a quadrilateral. In the VMs, the dividing line can be a solid line or a loop. The four subsequent areas may be left empty or have a central dot for each area. Specific examples at top of Pisces and the circular text markers on White Aries. Otherwise, they're everywhere.
