Hi, B. Oh, no! I am learning while drawing
! I am just trying to remember the vessels that I read when I was a child, or the old movies in W&B TVs (in my country, TV was in B&W at least until the Soccer World Cup of 1978: Poland vs Peru, 1-0, the next Cup was even worst against the poles: 5-1
!). For example the first reference of this drawing was (for me) in the famed novel by James Clavell "Shogun".
Portugal was the first Western maritime power involved in the trade, at least in a considerable scale, with Far East. A well known type of sailing vessels involved in the trade with Japan were the famed "black ships", or Kurofune, named in this way by the japanese because the hull was painted with pitch. Later, the term kurofune was used in Japan to name all the western ships despite their nationality.
The Black Ships, or Nau do Trato ("Trade Ships") were very big carracks, with a solid construction with the best woods avilable in western India, able to withstand the weather, winds and seas of the far eastern route between Goa, Macau and Nagasaki. This type of ship is very represented in the japanese art of the late XVI - early XVII centuries, as part of the "Nanban" ("southern barbarians" as portuguese and spaniard misionaries and traders arrived form the southern routes) art.
A pair of comments: I depicted the vessel without the green and white portuguese flag used in the eastern waters, because the Nau do Trato is from the late XVI century. Instead she is flying a portuguese flag with the well known "quina", the 5 balls arranged in cross typical of Portugal. The other interesting fact is that despite being almost universally represented in modern (at least from the XX century) portuguese art and models with huge red crosses in almost all the square sails (the crosses were from the Order of Christ, the Portuguese Templars), in the Nanban art, the crosses were absent (despite small detailes usually depicted, from the beard and moustaches of the portuguese, to the matchlock mechanisms of the muskets, and maritime details such of the rigging). Also, in old western pictures of the era (XVII century), the crosses are lacking. For that reason is that I prefer to avoid the red Order of Christ cross in the main sails of the carrack depicted here, but instead is flying the flag of that order in the foremast. Cheers.
