details. The House of Romanov itself used a unique yerikhonka called the , based on the royal helmet of Michael I (once mistakenly believed to have belonged to Alexander Nevsky, hence the name). Asian noble families non-Slavic origin who were integrated in the Empire were also allowed an ethnic helmet, usually a , similar to the yerikhonka in shape but rounder and with an obtuse tip. In the modern Russian Federation, the Russian Heraldic Council allows both Western and ethnic helmets (called sheloms in modern Russian heraldic language), but only in their simplest forms, and stripped of any details that may be perceived as symbols of nobility. For Western helmets, this means using commoner kettle hats as opposed to the more aristocratic open and close helmets, while sheloms are to be used without nasal bars, cheekpieces or neck guards, which were sometimes found on older "ethnic" helmets. On the other hand, a commoner helmet may be complemented with a mail coif below. All colours except for steel are forbidden, with the exception of the lining, for which other tinctures may be used (purpure is recommended). However, none of these restrictions apply to direct descendants of old Russian aristocracy, who can use the same helmets as their ancestors alongside the rest of their family arms. Both in Imperial and republican Russian heraldry, the direction of the helmet plays no role: whether the helmet is portrayed affronty or turned to the right depends on the shape of the crest. Canada In Canadian heraldry, helmets play little role and are not blazoned; therefore, the armiger can display their helm in whatever style they choose. One notable example of a non-traditional helmet used in Canadian heraldry is the arms of Julie Payette, a former governor general of Canada, which bears an astronaut's helmet as the helm. Other examples include nasal helmets, Corinthian helmets, parka hoods, and United Nations peacekeeping helmets. Belgium In Belgian heraldry, barred helms are most commonly used, and are not reserved for the nobility like in some jurisdictions. They most often have gold bars, as well as a gold collar and trim. They are often lined and attached. Ecclesiastical In the Roman Catholic Church, clerics entitled to a coat of arms use a galero instead of a helmet, which is considered too belligerent for men in holy orders. In the same way, clerics of the Anglican Communion entitled to a coat
