Ancient Egyptian glass was made especially in Akhenaten’s new capital as effulgent signs of the pharaoh’s solar-based beliefs. Millennia later, the iconography and colors of “sunlight” and “moonlight” windows illuminated both sacred and secular spaces, as seen here beneath a Coptic dome. Today, hand-blown Muski glass carries on the tradition; even these manufactured waterpipes reprise age-old motifs and hues in their glass bowls.
