The Collaborative International Dictionary of English v.0.48:

Tramontane \Tra*mon"tane\, a. [OF. tramontain, It. tramontano,
   L. transmontanus; trans across, beyond + mons, montis,
   mountain.]
   Lying or being beyond the mountains; coming from the other
   side of the mountains; hence, foreign; barbarous.
   [1913 Webster]

   Note: The Italians sometimes use this epithet for
         ultramontane, and apply it to the countries north of
         the Alps, as France and Germany, and especially to
         their ecclesiastics, jurists, painters, etc.; and a
         north wind is called a tramontane wind. The French
         lawyers call certain Italian canonists tramontane, or
         ultramontane, doctors; considering them as favoring too
         much the court of Rome. See Ultramontane.
