A pair of andirons are a metal stand, used for holding logs in a fireplace; they are modernly also known as “firedogs”. Andirons are found in period rolls, in the attributed arms of the King of Ethiopia, mid-16th C. [NW 92].
Period heraldic examples show andirons conjoined in pairs, frequently decorated with animal or human heads; the type of heads should be specified in the blazon. The illustration shows a pair of dog-headed andirons.
