The origin of the drop dates back to ancient Greece, where it was used as a unit of weight for measuring honey. The Greek philosopher Aristotle (384-322 BCE) wrote about the use of drops in his work " Historia Animalium". The term "drop" has been used consistently since then, with slight variations in its definition and usage.

In ancient Rome, the drop was used as a unit of weight for measuring wine, oil, and other liquids. The Roman naturalist Pliny the Elder (23-79 CE) mentioned the use of drops in his book "Naturalis Historia". During the Middle Ages, the drop continued to be used in Europe, particularly in England and France.

With the introduction of the metric system in the 19th century, the drop was replaced by more precise units of measurement. However, it has continued to be used in certain contexts, such as in the wine industry, where a "drop" is still used to measure the quantity of wine poured into a glass.
