Don Juan Carlos and doña Sofía greeted one by one to more than three hundred members of an expedition, after the Queen was given an edition of the 'Quijote' in Greek and the King was receiving, of Miguel de la Quadra Salcedo's hands, a letter that there have written to him four nuns Basque nuns of the order of St Clara who live for thirty years in Ayacucho.
The members of an expedition, many of them dressed in typical suits of their countries, sang for the Kings a Mexican song of the XVIIth century and other one in suahili, that dona Sofía accompanied touching palms.
