Lacerna
(practically identical with the Greek
χλαμύς). The Latin
term for a coarse, dark-coloured cloak, fastened on the shoulder by a brooch, which was in use
as a protection against rain. It was provided with a hood. In later times the name was given
to a light and elegant mantle, either white or dyed in Tyrian purple, which was worn over the
toga to complete the costume at games or other outdoor occasions. In the time of Augustus, who
forbade its use in the Forum or Circus, it formed part of the military uniform. It was
afterwards commonly worn even in Rome itself.
