Serafino Serrati

Information regarding Serafino is limited. Born in the 18th-century in Florence to a respectable family, he appears to have studied physics and botany. He is thought to have been the professor of experimental physics in his monastery.

Among his preferred studies was to find ways to direct the movement of globi areostatici, today in English referred to as hot-air balloons. It is said that his fellow monk Rabatta and Serrati were the first Florentines to become air-bound by globes. In addition, according to a biographer he was the first to apply the force of the vapor in lumber to move in the sea^[1] An article by Jouffroy d'Ambrans reported on his barchetto a fuoco (ship on fire).

He was said to have been adept and diligent in his monastic responsibility. One anecdote is that once upon hearing the bells calling the monks to choir as part of the liturgy of the hours, Serrafino would rush over still wearing the apron he was using while at work at some chemical oven. The editor of his letters remarks on his modesty and humility, and dismissal of world fame.^[2]

Among his reports published in life are the following nine communications:^[3]

• Regarding observations in the choice of flammable air
• Describing a two-burner retort to decompose wine spirit into flammable air
• Which describes a model to form an aerostatic globe with a conical shape, without making seams that it does not lose the air that is introduced into it
• Which explains the guiding of an aerostatic globe [balloon] in any direction, and to any height
• Representation of a flush scale, without friction
• About a pneumatic machine powered by mercury
• Description of a positive and negative conductor, and of an electrophore without resins
• Description of a boat powered by fire, which with that force, moves without wind(power)
• Describing a reverberating oven, for the use of baking bread.
