A mosaic of six, deep, CCD images in the light of the [O III] 5007 A nebular emission line has been obtained with the 1.3-m Skinakas (Crete) telescope of the filamentary nebulosity surrounding P Cygni. The [O III] 5007 A line discriminates against confusing galactic H II regions along the same sight-lines and the new mosaic did not include the 4.8 mag. central star; a source of artifacts in the previous lower angular resolution observations. New giant `lobes' and `shells' are found to be clustered around P Cygni which must be the relics of historic eruptions between 2400 and up to ~10^5 yr ago.
