These symbols 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.
A probable explanation of the confusion between the lectisternia and genuine old Italian ceremonies is that, as the lectisternia became an almost everyday occurrence in Rome, people forgot their foreign origin and the circumstances in which they were first introduced, and then the word pulvinar with its associations was transferred to times in which it had no existence.
Pulvinar lives actually in the alimentary canal of a species of Antedon.
