Poetry. PORTUGUESE SAILOR BOY is a fragmentary history of the bloodline of the Portuguese explorer, Vasco de Gamma. The bloodline motif plays out in a series of scenes of an unnamed contemporary relation--in symbolic forms like nautical maps and paint-by-numbers frigates. The narrative centers on the wayfaring of his character, which reveals a life of accidental achievement as well as unadvertised follies, and neither ascends nor descends to an end.
