The author specifies that the Leo c1 could be replaced by a Vao, but the diagram would then show a promotion Vao..}
2 - 6# with sparrow
Dietrich, St2018
white SWd6d3g4 Se4 Ke7
black Kd5
#6 (5+1)🨊d6, d3, g4: Sparrows
: The Sparrow is a Grasshopper at 135 degrees or - 45 degrees.
Clearly, the Sparrow d3 can, using the jump d5, go to c4 (d6-d5-c4= 135 degrees, d3-d5-c4= 45 degrees)..
The d6 Sparrow can, using the d5 jump, go to c6 or e6 (d4-d5-c6= 135 degrees, d6-d5-c6= 45 degrees)..
Zoological summary :
With an animal on d3 and a jump on d6, here's where the animal can go: -- grasshopper: d7 -- moose: c7, e7 -- eagle: c6, e6 -- sparrow: c5, e5 -- hamster: d5
Complete rosette around the jump.

3 - 2# with roses
Boyer, JP.1976

black Kg2 Ph3h4h5c5f7 Ra7a3 Qc4 Bb2 Sb1 BRb7
#2(10+12)g7, d6, d1, b7: Rose
: Extended rounded Knight
Rose d1 protects Rh1 via f2.
"Two lines of the chessboard can intersect at two points" (JPB).
In fact, the Rose g7, although pinned by Bb2, can be unpinned on d4 (via f5) or c3 (via e8-c7-b5),
by a path other than the diagonal.
Similarly, the Rose b7, pinned by the Ba8, can go to f3 (via a5-b3-d2) or,
after the Rod6's departure, on e4, which it will not fail to do.
