Lyceum is a Latin rendering of the Ancient Greek Λύκειον (Lykeion), the name of a gymnasium in Classical Athens dedicated to Apollo Lyceus. This original lyceum is remembered as the location of the peripatetic school of Aristotle. Some countries derive the name for their modern schools from the Latin but use the Greek name for the ancient school: for example, Dutch has Lykeion (ancient) and Lyceum (modern), both rendered "lyceum" in English (note that in classical Latin the "C" in lyceum was always pronounced as a K, not a soft C, as in modern English).
The name Lycée was retrieved and utilized by Napoleon in 1802 to name the main secondary education establishments. From France the name spread in many countries influenced by French culture.
