As a token of his appreciation, Caesar "decreed that henceforth all apothecaries would be permitted to exhibit containers of colored liquids in their windows as a symbol of their calling."

Apothecaries in England had been competing with physicians since an act passed in 1542 permitted them to practice medicine along with anyone else.

To attract attention to themselves and to symbolize the mystery and art of their profession these chemists displayed show globes with solutions of colored chemicals.

to send more physicians and apothecaries to the colony.
In the early American settlements there was a shortage of health professionals; public officials, religious leaders, educators and household heads served as health advisors. Herbs and Indian remedies were used and apothecary shops were set up in large population centers. During the Revolutionary War medicine and pharmacy emerged as separate professions, and the first American Pharmacopoeia was printed in 1778. By the 19th century, pharmacists had stopped practicing medicine and even the name apothecary faded away. Pharmacies developed the warmth and comfort of country stores and were displaying show globes, which by 1789 were being exported to America. According to one writer, the only way pharmacies distinguished themselves from other stores was this unique sign. "

Although the show globe became a pharmacy symbol of mainly English-speaking countries, it did appear in a few other countries notably France.
Design and colors
Next to their origins, the greatest debate about show globes is what, if anything, the colors of the liquids symbolized. Red and blue may have indicated

. One belief was that if the globe was filled with red liquid there was a plague in town, but if it was filled with green all was well. Pharmacists could create vibrant colors with chemicals in their shops, often following a recipe book.
Most globes were plain glass, but sometimes they were punty cut or etched glass. Some had multiple stoppers, each stopper smaller than the one below, tapering to a small finial at the top. They could be freestanding or wall-mounted. If they were freestanding, they hung from a brass chain; the most elaborate had multiple tiers, each chamber containing a different color of water. It was not so much the pharmacists who were responsible for the evolution of show globes to works of arts, but American glass manufacturers. Pharmaceutical catalogs during the 1870s advertised numerous styles of show globes with each glass manufacturer developing his own design. A U.S. patent was granted in 1869 to Henry Whitney of

, for a show globe with a colored glass body with a neck and base of transparent uncolored glass. The purpose of this design was to eliminate the need to use colored liquids, which could leave a residue inside the bottle.
Though oil could be used to illuminate the colored glass panes in windows, gas lighting in the early 19th century led to the general use of show globes. They could be lit from the interior or placed in front of a gas jet. In the United States, globes were usually illuminated by a light placed behind them.
Decline

Despite many attempts to revive show globes, they have disappeared from American pharmacies. By the early 20th century, new stores shunned them, and they were disappearing from many older pharmacies. Renewed support for the globes in the 1930s moved the

However, a 1935 American news article notes "rarely is a show globe ever seen in a modern druggist's emporium".
Through the 1950s, ''American Druggist'' urged pharmacists to bring back the show globe, terming it "the greatest trademark ever invented."
