Glassblowing as a technical breakthrough in the making of glass occurred in the first century BC. Glass vessels could thus be made more easily and new shapes and decorations were produced. Inflating glass in molds that were carved with designs created vessels of varying shapes with complex decorations in relief on their surfaces.  Ennion, probably from Sidon in today’s Lebanon, was a master craftsman in one of the earliest glass workshops in the first century AD.  He was among the first glassmakers to incorporate his name into the inscription in the mold’s design and his pieces were well-known and popular.  His vessels have been found all over the ancient Roman world leading to the conclusion that they were traded throughout the Mediterranean.  Today there are just over 50 known pieces by Ennion in collections.  A small exhibition at the Metropolitan museum gathers 24 of them, many still intact, and highlights their delicacy, sophistication and timelessness. The show includes pieces by other makers of the period and is all together informative and beautiful.
