Coal is first mentioned in 1245; but the smoke was supposed to corrupt the air so much, that Edward I. forbade the use of that kind of fuel by proclamation; and among the records in the Tower, Mr. Astle found a document, importing that in the time of Edward I. a man had been tried, convicted, and executed, for the crime of burning sea-coal in London. Coal first came into general use in the north of England.[43] Wood billets, however, long remained the principal fuel of the south; and the contrivance for burning such fuel with economy was the first deviation in metal from the rude simplicity of the rere-dosse towards the close fire-grate. This consisted of useful iron trestles, called hand-irons, or andirons, formerly common in England, and yet occasionally to be met with in old mansions and farm-houses, under the appellation of _dogs_. Originally, these articles were not only found in the houses of persons of good condition, but in the bedchamber of the king himself. Strutt, writing in 1775, says: "These awnd-irons are used at this day, and are called cob-irons: they stand on the hearth, where they burn wood, to lay it upon; their fronts are usually carved, with a round knob at the top; some of them are kept polished and bright; anciently many of them were embellished with a variety of ornaments." In another place, giving an inventory of the bedchamber of Henry VIII. in the palace of Hampton Court, including awnd-irons, with fire-fork, tongs, and fire-pan, Strutt adds, "of the awnd-irons, or as they are called by the moderns, cob-irons, myself have seen a pair which in former times belonged to some noble family. They were of copper, highly gilt, with beautiful flowers, enamelled with various colours disposed with great art and elegance." At Hever Castle in Kent,--the family seat of the Boleyns, as well as the property of Anne of Cleves, and which Henry VIII. with matchless cupidity claimed in right of a wife from whom, previously to her being beheaded, he had been divorced,--is a pair of elegant andirons, bearing the royal initials H. A. and surmounted with a royal crown. And, in an inventory of Henry's furniture in the Tower of London, we find mentioned "two round pairs of irons, upon which to make fire in, and for conveying fire from one apartment to another." Shakspeare thus minutely describes a pair of andirons belonging to a lady's chamber:-- "Two winking Cupids Of silver, each on one foot standing, Depending on their brands nicely."--_Cymbeline._
