Investigations in the basement of the Egyptian Museum in Cairo led to the rediscovery of a coffin lid of unknown provenance belonging to smA-tAwy son of iaH-ms (JE.36806). The lid was covered with two textile layers made from linen that do not belong to the coffin lid. According to the excavation Journal of Otto Rubensohn, the coffin was found in a family tomb at Abusir el-Meleq, Northern Middle Egypt. This study aims to confirm that the coffin lid dates back to the Ptolemaic period and that its base is exhibited at the Egyptian Museum in Cairo with a different number (TR. 25/8/19/3). Non-destructive methods (Portable X-ray radiography, Reflectance Transformation Imaging (RTI), Environmental scanning electron microscopy (ESEM) and Fourier Transform Infrared Spectroscopy coupled with Attenuated Total Reflection (FTIR-ATR) were used to identify tool marks and carpentry technology used during the Ptolemaic era in ancient Egypt. The lid was composed of six pieces of Tamarix sp. wood that were joined together with scarf joints and wooden dowels. Only the outer surface of the lid was covered with ground preparation layers that had been applied directly on the wooden support by brush, hiding any tool marks that were clearly obvious in the inner side of the lid. The detailed study of the coffin that was made in the necropolis workshop is a good example of woodworking techniques applied during that period.

Abstract

This study focuses on one of the early examples of using the human shape in the third inner coffin. An ancient Egyptian anthropoid wooden coffin belonging to the Egyptian prince Amenemhât from the Middle Kingdom, Twelfth Dynasty - was found in Deir El Bersha, Egypt in separate parts (Kamal 1902, 14) in 1900 and was reconstructed sometime after it was transferred to the Museum in 1916.
The aim of this study is to document the structure and materials used in making the coffin. Preliminary investigations confirm that the anthropoid coffin of Amenemhât was made of sidr wood (Ziziphus sp.), the use of which has been documented only infrequently in complete wooden coffins.
The feasibility, effectiveness, and overall value of portable X-radiography were proven during the study of the coffin. It helped identify both the structure and the previous incompatible conservation, in which a large number of screws and nails had been used to reconnect the wooden elements. The detached wooden parts that had been joined together were covered with a paste to hide the previous restoration. On the left side of the head animal glue and calcium carbonate (CaCO3) were identified using XRD and FTIR spectroscopy.
Digital photography and ultraviolet (UV) and infrared (IR) imaging were used in the documentation of the wooden coffin.
Samples were studied under both optical microscopy and scanning electron microscopy (SEM) to obtain a more detailed observation of the condition and physical characteristics of the wood.

يتناول البحث دراسة تابوت خشبي ملون تم العثور عليه بالمقبرة رقم 35 بمنطقة الواقفة بواحة باريس بمحافظة الوادي الجديد - مصر، وذلك بناءا على ما ورد في سجل وارد الآثار الخاص بمتحف آثار الوادي الجديد و المحفوظ الآن به التابوت و مسجل تحت رقم 2610/39. تركز الدراسة على استخدام منهج متعدد الفحوص و التحاليل للتعرف على المواد التي استخدمت في صناعة هذا التابوت من نوع الخشب و كذلك أرضية التصوير المستخدمة و طبقة اللون المطبقة على أرضية التصوير سابقة الذكر و أخيراً الوسيط المستخدم، حيث تم استخدام التصوير الفوتوغرافي، المجهر الرقمي USB digital microscopy، المجهر الضوئي Optical microscopy، التصوير بالأشعة تحت الحمراء (IR)، التحليل الطيقي بالأشعة تحت الحمراء (FTIR )، التحليل بطربقة حيود الأشعة السينية (XRD)، حيث أن أهم ما تم التوصل إليه البحث أن اللون الأصفر المستخدم في التابوت عبارة عن مادتان مختلفتان التركيب الأولى هي أصفر الأربمنت (كبريتيد الزرنيخ As2S3)، والثانية هي أصفر الجوثيت (أكسيد الحديد المائي Fe2O3.nH2O)، كما تم تحديد التوزيع المكاني لمادة اللون الأزرق وهي الأزرق المصري في التابوت بالكامل دون أخذ عينات باستخدام تقنية التصوير بالأشعة تحت الحمراء (IR) ، بالإضافة إلى التعرف على جميع المواد المستخدمة في صناعة التابوت (موضوع البحث).
