marugawara　丸瓦

KEY WORD :　architecture / roofing tiles

Also written 円瓦. Also called *ogawara 男瓦, especially in the 6c-12c. Also called tsutsugawara 筒瓦 (pipe-shaped tile), or hanmaru tsutsugawara 半丸筒瓦 (half-cylindrical pipe-shaped tile). Semi-cylindrical roof tiles having a pronounced convex curve. The end of the tile that points toward the ridge has a lip *tamabuchi 玉縁 over which the front of the next tile fits snugly. These tiles are set over the seams of the broad concave tiles *hiragawara 平瓦. Rainwater flows over them into the concave tiles where it drains along the downward slope of the roof and runs off, minimizing problems of leakage. The length of the visible part of the half-cylindrical tile does not vary. Because it is slightly longer than the broad concave tile, fewer semi-cylindrical tiles need to be used. The measurements of all roof tiles differ according to type and period of production. Ordinary sized tiles are sometimes called namimarugawara 並丸瓦, and small tiles are called komarugawara 小丸瓦 or itomarugawara 糸丸瓦. Depending on shape, they are called cane-handle shaped tiles *tonemarugawara 利根丸瓦 or tsubamarugawara 鍔丸瓦.
