Lothair crystal refers to a specific type of medieval rock crystal relic or object that originated during the Lotharingian period, which was characterized by the rule of the Merovingian and Carolingian dynasties in the area known as Lotharingia (present-day regions of Germany, France, Belgium, Luxembourg, and the Netherlands) during the 6th to 10th centuries. It is named after Lothair II, the King of Lotharingia who reigned from 855 to 869.
These crystals were typically carved or sculpted into various intricate and ornate shapes, often taking the form of crosses, reliquaries, or small statues. Lothair crystal objects were highly valued for their transparent and translucent qualities, creating dazzling visual effects when light was refracted through them.
These crystals were cherished as sacred relics or amulets due to the prevalent belief in their supposed miraculous and protective properties. They were often considered holy due to their incorporation of relics such as bone fragments, cloth, or hair of revered saints or religious figures.
Today, Lothair crystals are highly sought after by collectors and historians due to their historical and cultural significance. Their delicate craftsmanship and artistic value make them valuable artifacts, providing insights into the religious and artistic practices of the medieval period. The term "Lothair crystal" is therefore used to designate a specific category of medieval rock crystal objects originating from the region of Lotharingia during a defined historical period.
The word "Lothair crystal" does not have a direct etymology since it is a pseudo-scientific term coined in the 19th century. It was named after the French king Lothair II (835-869) and gained popularity during that time. However, the term itself is not associated with any specific historical or linguistic origin. The crystal is believed to refer to a type of rock crystal, which might have been valued or associated with King Lothair II for unknown reasons.
