The lectisternium was an ancient Roman propitiatory ceremony, consisting of a meal offered to gods and goddesses. The word derives from lectum sternere, "to spread (or "drape") a couch." The deities were represented by their busts or statues, or by portable figures of wood, with heads of bronze, wax or marble, and covered with drapery. It has also been suggested that the divine images were bundles of sacred herbs tied together in the form of a head, covered by a waxen mask so as to resemble a kind of bust, rather like the straw figures called Argei. These figures were laid upon a couch (lectus), the left arm resting on a cushion (pulvinus, whence the couch itself was often called pulvinar) in the attitude of reclining. The couch was set out in the open street, and a meal placed before it on a table.

The duumvirs for the direction of religious matters, the lectisternium being then for the first time introduced into the city of Rome, for eight days implored the favour of Apollo and Latona, Diana and Hercules, Mercury and Neptune, three couches being laid out with the greatest magnificence that was then possible.
