The example above showed embattlements applied only to the upper edge of
the fess.
This is the default practice for bends, fesses, and chevrons embattled,
and presumably also for bends sinister embattled.
I'm not sure about chevrons inverted, though.
The upper-edge rule also seems to apply to fesses flory and trefly, chevrons
grady and potent, and bends flory, though some might dispute these.
But surprisingly, fesses and bends potent are decorated on both edges.
Indeed, in most
cases, the default is for patterns to be applied to
all edges of an ordinary. For instance, here is
Sable, a pale wavy
argent:
When all edges of a multi-edged ordinary are indented, the term
"dancetty" is used. For instance, here is
Sable, a pale dancetty
argent:
Notice that waves and dents on opposite sides of the pale are "in phase" so that
the width of the pale remains more-or-less constant. This is generally
true of complex lines applied to multi-edged ordinaries. The one exception
is bretessed which is identical to embattled except that the
battlements on opposite edges are 180 degrees "out-of-phase" with one another.
Here is Sable, a pale bretessed
argent:
Chevrons, fesses, and bends bretessed, naturally, have battlements on both edges.
To specify that a fess, chevron, or bend has embattlements on both edges that
are "in phase", the term "embattled-counter-embattled" is used.
Engrailed and invected edges, because of their asymmetry, require special
clarification. An engrailed ordinary has semi-circular "bites" taken
out of it, whereas an invected ordinary has semi-circular "bumps" added
to it. For instance, here is Sable, a chief engrailed
argent:
Divided fields engrailed are defined as follows:
