Pagan \Pa"gan\ (p[=a]"gan), n. [L. paganus a countryman,
   peasant, villager, a pagan, fr. paganus of or pertaining to
   the country, rustic, also, pagan, fr. pagus a district,
   canton, the country, perh. orig., a district with fixed
   boundaries: cf. pangere to fasten. Cf. {Painim}, {Peasant},
   and {Pact}, also {Heathen}.]
   One who worships false gods; an idolater; a heathen; one who
   is neither a Christian, a Mohammedan, nor a Jew.

         Neither having the accent of Christians, nor the gait
         of Christian, pagan, nor man.            --Shak.

   Syn: Gentile; heathen; idolater.

   Usage: {Pagan}, {Gentile}, {Heathen}. Gentile was applied to
          the other nations of the earth as distinguished from
          the Jews. Pagan was the name given to idolaters in the
          early Christian church, because the villagers, being
          most remote from the centers of instruction, remained
          for a long time unconverted. Heathen has the same
          origin. Pagan is now more properly applied to rude and
          uncivilized idolaters, while heathen embraces all who
          practice idolatry.

Pagan \Pa"gan\, a. [L. paganus of or pertaining to the country,
   pagan. See {Pagan}, n.]
   Of or pertaining to pagans; relating to the worship or the
   worshipers of false goods; heathen; idolatrous, as, pagan
   tribes or superstitions.

         And all the rites of pagan honor paid.   --Dryden.
