A Caravel.
(After a Painting of the sixteenth century, in the Monastery of the Mother of God at Lisbon.)
The store-ship was of more considerable size. Sernigi (p. 123) says she measured 110 tons; Castanheda credits her with 200. She may have been a so-called caravela redonda, that is a caravel which carried square sails on the main and fore-masts and triangular ones on the mizzen-mast and the bowsprit. This vessel was purchased of Ayres Correa, a shipowner of Lisbon.
The S. Gabriel and S. Raphael were specially built for this voyage. Bartholomeu Dias, who superintended their construction, discarded the caravel in which he himself had achieved his great success, in favour of square-rigged vessels of greater burthen, which, although slower sailers and less able to ply to windward, offered greater safety and more comfort to their crews. He took care, at the same time, that the draught of these vessels should enable them to navigate shallow waters, such as it was expected would be met with in the course of the voyage. The timber for these two vessels had been cut during the last year of the reign of King John, in the Crown woods of Leiria and Alcacer. The vessels having been completed, the King ordered them to be equipped by Fernão Lourenço, the factor of the house of Mines, and one of the most “magnificent” men of his time.[396]
No contemporary description or picture of these vessels has reached us, but there can hardly be a doubt that their type[397] is fairly represented on a painting made by order of D. Jorge Cabral, who was Governor of India from 1549 to 1550. This painting subsequently became the property of D. João de Castro. A copy of it was first published by the Visconde de Juromenha, who took it from a MS. dated 1558.[398] The fine woodcut in W. S. Lindsay’s History of Merchant Shipping (II, p. 5), from an ancient picture which also belonged to D. João de Castro, seems to be derived from the same source, but as the vessel carries the flag of the Order of Christ at the main, and not the Royal Standard, it cannot represent the flag-ship. At all events, it is not more authentic than either of the ships delineated in the drawing first published by Juromenha.
The supposed Armada of Vasco da Gama.
(From a Painting made by order of Jorge Cabral (1549-50.))
Authorities differ very widely as to the tonnage of these two vessels. Sernigi (see p. [123]) says they were of 90 tons each, thus partly bearing out Correa, who states that the three ships (including the Berrio) were built of the same size and pattern.[399] D. Pacheco Pereira[400] states that the largest of them did not exceed 100 tons; J. de Barros gives them a burthen of between 100 and 120 tons; whilst Castanheda allocates 120 tons to the flag-ship and 100 to the S. Raphael.
But whilst the authorities quoted dwell upon the small size of the vessels which for the first time reached India from a European port, and even give reasons for this limitation of burthen,[401] there is some ground for believing that the tonnage of Vasco da Gama’s ships, expressed according to modern terminology, was in reality much greater than is usually supposed. Pedro Barretto de Rezende (p. 151) may therefore have some justification when he states that these vessels ranged from 100 to 320 tons. Mr. Lindsay (loc. cit.) would go even further. The S. Gabriel, according to him, was constructed to carry 400 pipes, equivalent to 400 tons measurement, or about 250 to 300 tons register. He adds that Sr. E. Pinto Bastos agrees with him.[402]
In considering this question of tonnage, it must be borne in mind that “ton”, at the close of the fifteenth century, was a different measure from what it is at present. We learn from E. A. D’Albertis[403] that the tonelada of Seville was supposed to afford accommodation for two pipes of 27½ arrobas (98 gallons) each, and measured 1.405 cubic metres, or about 50 cubic feet. The tonel of Biscay was 20 per cent. larger. According to Capt. H. Lopez de Mendonça, the tonel at Lisbon measured 6 palmos de goa in length (talha), and 4 such palmos in breadth and height (parea), that is, about 85 cubic feet.[404] This, however, seems excessive, for my wine merchant tells me that two butts of sherry of 108 gallons each would occupy only 75 cubic feet. At any rate, these data show that the ton of the fifteenth century was considerably larger than the ton measurement of the nineteenth.
