Syntia / Cynthia / Cinthia

Syntia is a variant of Cynthia, a name derived from the Greek Kynthia (Κυνθία). Kynthia means 'from Kynthos', which was a mountain on the island of Delos. According to Greek mythology, the twin gods Apollo and Artemis (Diana in Roman mythology) were born on Mount Kynthos. Therefore, Cynthia became an epithet for Artemis, the goddess of the moon, the hunt, and childbirth.

The name Cynthia gained popularity in the English-speaking world during the Renaissance, particularly among poets and writers who were inspired by classical mythology. It has been used consistently since then, though its popularity has fluctuated. The spelling 'Syntia' is a less common phonetic variation.
