Rosette Patterns

Dihedral Patterns

Patterns with dihedral symmetry have rotational symmetry around a central point. The rotation can be 1/2 turn, 1/3 turn, etc., and the groups are correspondingly named D2, D3, ... In addition to the rotational symmetry, these patterns look the same when reflected.

D1
Central Dome, altar partition.
D1 is very common.

D2
All Saints Chapel, altar.
D2 is common.

D3
Pew.

D3
High altar, dome.

D4
East side, outdoors.
D4 is very common.

D5

(The stars)

All Saints, bolt.
One of the few examples of D5 symmetry which is not a five-pointed star embedded in another pattern.

D5
Part of a window

All Souls, ceiling.
D6 is very common.

D7, D14
East Transept, window.
The only example I've found.

D8
Floor.

D10
All Saints, altar.
The only example I've found.

D14, D21
Candleholder.
Depends whether you look at the outer or inner ring of candles.
