A very rare term used to describe a cross terminating in the heads on some animal. The type of animal should be noted in the blazon.
The “Ant” or more traditionally “Emmet” are rarely met with in heraldry. When they are used as a charge on a coat armor they are shown tergiant.
Heraldry does not often distinguish between Apes and Monkeys and their usual depiction is quite stylized and may be difficult to recognize.
Ascents are steps, like those on a dias. The same graphic element can be seen as the base of the cavalry cross, however, as a part of that charge they are called griece.
Angels, though very frequently met with as supporters, are far from being usual, either as a charge upon a shield or as a crest.
