What a serene picture depicted on this card, in the midst of the grey isolation and pain of the other Swords! It does look hopeful and optimistic: like BodhiSeed, I can't help but reminisce on the joy of past journeys and the excitement of future travel. But I always look for both a lesson and warning in each card, so here's my "negative" interpretation.

This map is the Orbis Geographica, created by Hendrik Hondius circa 1630. A traditional meaning for the Six of Swords is a "regretful" transition, a journey you'd rather not take, and the 17th century had its share of mournful naval expeditions. 1620 saw the establishment of Plymouth Colony by the Pilgrims, who encountered fierce storms during their flight from England. Large-scale movement of African slaves to the British Caribbean began in the 1640s. And the buccaneering period (c. 1650-1680) kicked off the Golden Age of Piracy in the Caribbean and eastern Pacific.
The journey of life, of course, sometimes takes us places we would prefer not to go. At least most of us can be thankful that our lives are better than the folks I listed above!
