Symbols of past glory, of empire and and global reach, caravels and carracks still sail in Lisbon, woven in Persian 17th century carpets, painted on Japanese screens or even depicted in pavement cobblestones. All reminders of nearly six centuries of empire, for good or for bad. Seeing these emblematic ships at a moment when the Brexit furore is reaching a crescendo in England made me ponder the parallels of the erstwhile Portuguese and British Empires.
