Article: The term pewter covers a variety of alloys consisting primarily of tin. As a pure metal, tin was much too soft to be used for any practical purpose. However, in the Bronze age, tin was a rare metal and, in many parts of Europe and the Mediterranean, was often valued higher than gold. To make jewelry, forks and spoons, or other objects from tin, it was usually alloyed with other metals to increase its strength and hardness. These metals were typically lead, antimony, bismuth or copper. These solutes sometimes were added individually in varying amounts, or added together, making a wide variety of things, ranging from practical items, like dishes, surgical tools, candlesticks or funnels, to decorative items such as ear rings and hair clips.

Article: Very few early Byzantine mosaics survived the Iconoclastic destruction of the 8th century. Among the rare examples are the 6th-century Christ in majesty (or Ezekiel's Vision) mosaic in the apse of the Church of Hosios David in Thessaloniki that was hidden behind mortar during those dangerous times. Nine mosaic panels in the Hagios Demetrios Church, which were made between 634 and 730, also escaped destruction.
