Pope John XXIII And Rainiers A papal audience is accorded Prince Rainier and Princess Grace of Monaco by Pope John XXIII, a 25-minute private conversation that touches off an odd rumor - quickly denied - of plans for a Vatican high seas fleet. Prince Rainier, in uniform, and Princess Grace, with black veil, walk with clergymen, kneel in respect before the Pope. Two women wearing long black veils each kiss the Pope's hand. The pope makes the sign of the cross (blessing?). Grace and her husband depart, bowing again to the pope as they leave.
