The term corolla or 'corollæ' appears in a chapter title in Pliny the Elder's Naturalis Historia: "Who invented the art of making garlands: When they first received the name of 'corollæ,' and for what reason."
The term was used to describe a crown made from branches and twigs of trees worn by victors in sacred contests. Later, flowers were used in combinations of colors and smells to "heighten the effect". Pliny credits this refinement of the art the painter Pausias who was imitating the garland maker Glyccra (a female, sometimes associated with Horace). Glyccra challenged Pausias to a contest where she would repeatedly vary her designs, and thus it was (as Pliny described it) "in reality a contest between art and Nature". This invention is traced only to later than the 100th Olympiad via Pausias paintings.
These "chaplets of flowers" became the fashion, evolving into the Egyptian chaplets, made of ivy, narcissus, pomegranate blossoms. According to Pliny, it was P. Claudius Pulcher who introduced winter corollæ, made for the time at which flowers and plant matter are not available of thin laminæ of horn stained various colors. 
Slowly, the name was introduced at Rome, these garlands being known there at first as "corollæ" (the diminutive of corona), a name Pliny says was given them to express the "remarkable delicacy of their texture."
Later, these head dresses were made of thin plates of copper, gilt or silvered, and were called "corollaria", as introduced by Crassus Dives as a way to confer a greater honor when receiving them.
In Chapter 5 of Naturalis Historia, titled "The great honour in which chaplets were held by the ancients" Pliny explains the how these head dresses were perceived:
|“||Chaplets, however, were always held in a high degree of estimation, those even which were acquired at the public games. For it was the usage of the citizens to go down in person to take part in the contests of the Circus, and to send their slaves and horses thither as well. Hence it is that we find it thus written in the laws of the Twelve Tables: "If any person has gained a chaplet himself, or by his money, let the same be given to him as the reward of his prowess." There is no doubt that by the words "gained by his money," the laws meant a chaplet which had been gained by his slaves or horses. Well then, what was the honour acquired thereby? It was the right secured by the victor, for himself and for his parents, after death, to be crowned without fail, while the body was laid out in the house, and on its being carried to the tomb.||”|
Pliny continues the explanation to describe the severity in which the rules of the wearing of the chaplets were enforced by the "ancients":
- L. Fulvius, a banker, having been accused, at the time of the Second Punic War, of looking down from the balcony of his house upon the Forum, with a chaplet of roses upon his head, was imprisoned by order of the Senate, and was not liberated before the war was brought to a close.
- P. Munatius, having placed upon his head a chaplet of flowers taken from the statue of Marsyas, was condemned by the Triumviri to be put in chains. Upon his making appeal to the tribunes of the people, they refused to intercede in his behalf
- The late Emperor Augustus, who, in her nocturnal debaucheries, placed a chaplet on the statue of Marsyas, conduct deeply deplored in the letters of that god.
It was emperor Augustus's only daughter Julia whom once after placing a corolla upon the head of a statue was exiled on grounds of breach to the newly legislated morality laws, this was also a direct link to the assumption of Augustus as the "father" of the whole society and thus he made an example of his daughter.
