Hi Torsten,

Thanks for the confirmation. That obviously explains the observed behaviour very simply.

Not intuitive to me. I would have thought the stencil was rotated in this case about its axis of symmetry. But I guess lily[ond does not really know the item, just a stencil, is a 'circle' with special geometrical properties. But once one knows about this, it's all very clear. Indeed. as I thought, lilypond has not the mathematical nicety of Postscript in this particular area (indeed, why should it? It is my mistake to think that.).

The bounding box of a circle actually is a square.
But, after rotation, the resulting markup/stencil will have a new bounding
box (with vertical height and horizontal width) large enough to contain the
original bounding box (all objects are considered as boxes, no matter what
their actual shape may be).
