摘要：Ethiopian icons played an important role in Ethiopian arts in the period between mid-fifteenth centuries and the twentieth century. The religious ties between Egypt and Abyssinia witnessed a prosperous phase in the period after the introduction of Christianity in the fourth century AD. Several previous studies have dealt with Ethiopian icons in terms of their artistic and pictorial side; however, there are no similar studies in Egypt discussing their manufacturing techniques, deterioration, and proper treatment and conservation methods. Therefore, this study aims to study the manufacturing technique of an anonymous Ethiopian icon (registration number 4881) kept in the storagerooms of the Coptic Museum in Cairo. This icon depicts St. George riding his horse and handling in his hand spears in the form of an X. Its dimension 123.5 cm long, 113.4 cm wide . The analytical techniques utilized in this study were optical microscopy (OM), scanning electron microscopy (SEM) equipped with an energy dispersive X-ray detector (EDS), X-ray diffraction (XRD), and Fourier transform infrared spectroscopes (FTIR). The results indicated that the icon was done on a cotton canvas, and the identified pigments are the blue of lapislazuli, yellow of lead chromate, white of anhydrite and black of carbon black from bones. The ground layer is made of anhydrite (calcium sulphate).
