On the 15th of November, 1624, he embarked at Goa in a ship bound for Muskat, from whence he proceeded up the Persian Gulf to Bassorah. Here he hired mules and camels, and provided all things necessary for crossing the desert; and on the 21st of May, 1625, departed, being accompanied by an Italian friar, Marian, the Georgian girl, and the corpse of Maani. During this journey he observed the sand in many places strewed with seashells, bright and glittering as mother-of-pearl, and in others with bitumen. Occasionally their road lay over extensive marshes, covered thickly with reeds or brushwood, or white with salt; but at this season of the year every thing was so dry that a spark falling from the pipe of a muleteer upon the parched grass nearly produced a conflagration in the desert. When they had advanced many days’ journey into the waste, and beheld on all sides nothing but sand and sky, a troop of Arab robbers, who came scouring along the desert upon their fleet barbs, attacked and rifled their little caravan; and Della Valle saw himself about to be deprived of his wife’s body, after having preserved it so long, and conveyed it safely over so many seas and mountains. In this fear he addressed himself to the banditti, describing the contents of the chest, and the motives which urged him so vehemently to desire its preservation. The Arabs were touched with compassion. The sight of the coffin, enforcing the effect of his eloquence, interested their hearts; so that not only did they respect the dead, and praise the affectionate and pious motives of the traveller, but also narrowed their demands, for they pretended to exact dues, not to rob, and allowed the caravan to proceed with the greater part of its wealth. On arriving at the port of Alexandretta another difficulty arose. The Turks would never have allowed a corpse to pass through the custom-house, nor would the sailors of the ship in which he desired to embark for Cyprus on any account have suffered it to come on board. To overreach both parties, Pietro had the body enveloped in bales of spun cotton, upon which he paid the regular duty, and thus one further step was gained. After visiting Cyprus, Malta, and Sicily, where he remained some short time, he set sail for Naples. Here he found his old friend Schipano still living, and after describing to him the various scenes and dangers through which he had passed, moved forward towards Rome, where he arrived on the 28th of March, 1626, after an absence of more than twelve years.
