This man is a Qasim, and a descendant of the Hajji/Khwaju Qasim who built the birka (small reservoir) where Shah Abbas halted (159km from Isfahan). He has distinctively hazel eyes (sadly not shown at their best here in the bright midday sun), and all his relatives – perhaps including Khwaju Qasim, over four hundred years ago – either have hazel or turquoise-blue eyes.
