  NGC 1360 is a large planetary nebula (PN) without an obvious shell
morphology. We have analyzed H-alpha images and high-dispersion echelle spectra
of NGC 1360 in order to construct spatio-kinematic models and to determine its
density distribution. The best-fit model indicates that NGC 1360 is a prolate
ellipsoidal shell whose major axis is twice as long as its minor axis and is
tilted by 60 arcdeg with respect to the line of sight. The large kinematic age
of the shell, ~10,000 yr, and the low density of the nebula, <130 H-atom cm^-3,
imply that NGC 1360 is an evolved PN and has begun to merge with the
interstellar medium. The observed morphology and surface brightness profiles of
NGC 1360 can be described well as a thick shell with a Gaussian radial density
profile without a sharp inner edge, indicating a lack of on-going compression
by a fast stellar wind. The FLIERs observed in NGC 1360 near the end of its
major axis expand faster and are younger than the nebular shell.
