There are two published copies of the voyage which constitutes the essence of our present chapter. The earliest of these was published by _Aldus_ at Venice in 1540, along with other tracts of a similar nature, under the name of _A Voyage from Alexandria to India_[211]. The other was given by _Ramusio_ in the first Volume of his Collection, under the title of _A Voyage written by a Venetian officer_[212] of the _Gallies, who was carried prisoner from Alexandria to Diu in India, &c_. These copies differ in several respects besides the title. That by Ramusio is altered in several places both in the substance and diction, which in many parts of that edited by Aldus is obscure. Yet that edition is of use to correct some errors of the press in Ramusio. Our translation is from the text of Aldus, but we have marked the variations in that of Ramusio, and have likewise divided the journal into sections, as done by Ramusio. [Footnote 211: The title of the book published by Aldus in which this voyage is contained is Viaggi alla Tana, Persia, India, &c.--Astley, I. 88. a.] [Footnote 212: The word designating the rank of this officer in Ramusio is _Comito_, signifying Boatswain, or the officer who superintended the galley-slaves.--Ast. I. 88. b.] Though not made by the Portuguese, this voyage certainly claims to be inserted in this place, as having a near connection with their affairs; besides which, it serves to complete the information contained in the article next succeeding; as the present voyage was made along the eastern side of the Red Sea, while the other was along its western side: So that the two together give a tolerable account of the whole of that sea; and they are in fact the more valuable, as being the only minute journals or relations extant of voyages performed along the whole length of the Arabian Gulf; except that by Mr Daniel in 1700, which is very superficial. Yet geographers, with the exception of M. de Lisle, and one or two since, seem to have made no use of these helps. It is however very surprising that neither of these two journals take the smallest notice of that great bay or arm at the head of the Red Sea, anciently called the _Elanitic_, a little to the east of _Tor_ or _Al Tur_, which passing by the foot of Mount Sinai, penetrates a great way into Arabia. This has been described by the Arabian geographers, and confirmed by two eminent travellers of our own country, Dr Shaw and Dr Pococke, both of whom have delineated it in their maps[213]. [Footnote 213: The topography of the Red Sea has been much improved by Bruce, in his Travels in Abyssinia, and since him by Lord Valentia in his Travels in India.--E.]
