A hand is a human appendage used for grasping and holding; it is found in the canting arms (French main) of Malmains, c.1275 [ANA2 469]. The default hand is the dexter hand, the default posture is apaumy and couped. Sinister hands are very frequently found in period armory, as well. While Society armory grants no difference between left and right hands, current practice is to explicitly blazon the handedness. The hand is unclothed by default; sometimes it is found issuant from a cuff, which fact is blazoned.
Hands are found in other postures besides apaumy. The hand may be “clenched”, forming a fist; indeed, this form may be simply blazoned a “fist”, as in the canting arms (German Faust) of Fausten, 1605 [Siebmacher 211]. A variant of this form is a fist with the index finger extended, as in the arms of Angiolini, c.1550 [BSB Cod.Icon 278:273].
A pair of hands “in birkat kohanim” has the hands slightly tilted towards each other, the fingers spread but with the index and middle fingers together, as well as the ring and little fingers. This hand gesture is used as a Jewish blessing. The motif is found in period armory, in the arms of Rabbi Abraham Menachem Rapoport, d.1596 [Nathan Ausubel, Pictorial History of the Jewish People].
Similarly, a “hand of benediction” is a gesture used in Christian blessing: the hand is apaumy, with the thumb and two fingers upright, the other fingers curled into the palm. It’s quite frequent in books of hours, and is depicted in modern heraldry texts [Guide 131], but makes very few appearances in period armory: e.g., the crest of Boyd, 1582 [Dunvegan Armorial, fo.253], or the attributed arms of Prester John, c.1530 [BSB Cod.Icon 391:55]. A vested arm ending in a hand of benediction is found in the episcopal arms of Sechau or Seckaw, 1605 [Siebmacher 12].
Of postures peculiar to the Society, there is the hand “aversant”, the opposite of apaumy, with the back of the hand to the viewer. Other hand variants include the “hand of Fatima”, a two-thumbed hand, a symbol of Islam; and the “hand of glory”, a hand enflamed, which is not permitted in Society heraldry.
In British heraldry, a sinister hand apaumy gules is used as the augmentation for baronets; and the “hand of Ulster”, a dexter hand apaumy gules, is a reserved charge in Irish heraldry. For these reasons, Society armory disallows the use of red hands apaumy on white backgrounds, when they appear to be in the form of an augmentation.
