The Biographie Universelle says it was Don Pedro of Castile about whose cognomen there was some difference of opinion; a defence of him being written in 1648 by Count de Roca, ambassador from Spain to Venice, entitled, ‘El Rey Don Pedro, llamado el Cruel, el Justiciero, y el Necessitado, defendido.’ It is he, I suppose, figures in the ‘Medico de su Honra.’ He flourished at the same time, however, with his namesake of Arragon.
