After his return from the perilous journey to Bordeaux, Pedro III., with the concurrence of the Cortes of Aragon and Catalonia, came to a very important decision. His queen, daughter and heir of King Manfred, was to proceed to her Sicilian possessions and thus ensure the loyalty and devotion of the people who had been delivered from the tyranny of Charles of Anjou by her husband. She was to be accompanied by her two younger sons, Jayme and Federigo. The latter was quite a young boy, there being an interval of seven years between the two brothers. The eldest son, Alfonso, was to remain with his father. As a measure of State policy it was wise and judicious. But the separation was a sacrifice to duty and a cause of grief and anxiety both to En Pedro and to Queen Constance. They never saw each other again. A fleet was fitted out at Barcelona with great care, and every known appliance for ensuring a safe voyage was brought into requisition. Even the use of compasses is mentioned by Muntaner. The discovery has usually been attributed to one Flavio Gioia of Amalfi and to the year 1302. But here we have evidence of their use a quarter of a century earlier; while at about the same time Raimundo Lulio of Majorca (I quote from a note of Antonio de Borafull) wrote these words in his work ‘De Contemplatione’: ‘Sicut acus per naturam vertitur ad septentrionem dum sit tacta a magnete.’ The ships, thus quite exceptionally provided and well manned with Catalan crossbowmen, were to be under the guidance of those trusty sea-captains, Ramon Marquet and Berenguer Mallol.
