Fess of five fusils (Period)

A fusil, in its correct medieval sense, is a single segment of an indented ordinary:  i.e., a “fess indented”, a “fess fusilly”, and a “fess of five fusils (conjoined)” were equivalent blazons and yielded the same emblazon (as illustrated).  The fusil can thus have no independent existence outside an indented ordinary.  Medieval blazons called a single geometric rhombus shape a “lozenge”, and never a “fusil”, no matter what its proportions; current Society blazons follow this precedent.  (Nonetheless, some early Society blazons followed the Victorian assumption that a fusil was a “skinny lozenge”:  an independent charge, somewhat narrower than a lozenge.)  For related charges, see lozenge.
