If it was only in the south that Moorish masons built in stone or brick, their carpenters had a much wider range. The wooden ceilings of as late as the middle of the seventeenth century may show no Eastern detail, yet in the method of their construction they are all ultimately descended from Moorish models. Such ceilings are found all over the country, but curiously enough the finest examples of truly Eastern work are found in the far north at Caminha and in the island of Madeira at Funchal. [Sidenote: Aguas Santas.] The old romanesque church at Aguas Santas near Oporto has a roof, simple and unadorned, the tie-beams of which are coupled in the Moorish manner. The two beams about a foot apart are joined in the centre by four short pieces of wood set diagonally so as to form a kind of knot. This is very common in Moorish roofs, and may be seen at Seville and elsewhere. The rest of the roof is boarded inside, boards being also fastened to the underside of the collar beams. [Sidenote: Azurara.] At Azurara the ties are single, but the whole is boarded as at Aguas Santas, and this is also the case at Villa do Conde and elsewhere. In the palace chapel at Cintra, already described, the boarding is covered with a pattern of interlacing strips, but later on panelling was used, usually with simple mouldings. Such is the roof in the nave of the church of Nossa Senhora do Olival at Thomar, probably of the seventeenth century, and in many houses, as for instance in the largest hall in the castle at Alvito. From such simple panelled ceilings the splendid elaboration of those in the palace at Cintra was derived. [Sidenote: Caminha.]
