Perishable: Cordage AMNH 29.0/8629

Cordage, Accession AMNH29.0, Catalog #8629. Morris FS 2120. Analyzed by Laurie Webster, 2006. Description. Measurements: Images: AMNH 29.0/8629A: apocynum or yucca cordage. Recovered from Earl Morris' excavation of Room 78, Aztec West Ruin. Earl Morris’ description of Room 78 at the time of excavation is as follows. “About three-fourths of a cord of cedar splints such as were used in the construction of ceilings had been left in Room 78, covering the entire area of the chamber, but deepest against the north wall. …. One pine log, extending north and south, had supported the ceiling. The small poles were of cottonwood. This ceiling had remained intact until after the ruin was reduced to a mound. Finally,….the log rotted off next to the north wall, and permitted that end of the ceiling to settle down upon the mass of splints…. Where the timber entered the south wall it broke, but did not fall. An extensive deposit of vegetable refuse had been thrown into the room above Room 78. When the ceiling settled, much of this ran through and around it, and, together with dust and sand….eventually completed the filling of the room except for a cavity, triangular in cross-section, across the south side. … [Explanation of artifacts]….Between the refuse and the surface of the mound were elements of the second ceiling; partially charred wood and fire-hardened adobe. Numerous peeled willows and their impressions in adobe clods indicated that in the second ceiling there had been an ornamental finish of these slender sticks closely placed on top of the layer of small poles. Ventilators are present in the ends of the north walls.” (Morris 1928: 326-327) Reference: Earl Morris, 1928, Notes on Excavations in the Aztec Ruin, Volume XXVI, Part V, Anthropological Papers of the American Museum of Natural History, New York.

影像资料AMNH 29.0/8629A：罗布麻（Apocynum）或丝兰（Yucca）绳具。该绳具出土自厄尔·莫里斯（Earl Morris）对阿兹特克西遗址（Aztec West Ruin）78号房间的发掘遗存。
厄尔·莫里斯在发掘期间对78号房间的记述如下：
“约四分之三考得的雪松细木条——这类木条曾被用于搭建天花板——铺满了78号房间的整个地面，且在北墙附近堆积最厚。……一根沿南北向延伸的松木原木曾支撑起天花板，小型桁杆则由三角叶杨（Cottonwood）制成。该天花板直至遗址沦为土丘后仍保持完整。最终，紧邻北墙的原木发生腐烂断裂，致使天花板的该端沉降至细木条堆之上……木材嵌入南墙的位置发生断裂但并未脱落。大量植物残屑被丢弃在78号房间上方的区域。当天花板沉降时，大部分残屑穿过并围绕天花板散落，连同尘土与沙石……最终填满了除南侧一处横截面呈三角形的空腔之外的整个房间。……[文物说明]……在残屑堆积与土丘表面之间存在第二层天花板的遗存：部分炭化木材与经火烧硬化的土坯。大量被剥皮的柳树及其在土坯块上留下的印痕表明，第二层天花板的表层装饰由紧密排布的细柳枝构成。北墙端部设有通风口。”（莫里斯，1928：326-327）
