The name Alethea has its roots in ancient Greek, originating from the word "aletheia" which translates to "truth" or "disclosure." This name gained prominence during the Classical period in ancient Greece, around the 5th century BCE.

In Greek mythology, Aletheia was the personification of truth, often depicted as a beautiful maiden. The concept of truth held great significance in Greek philosophy, with thinkers like Socrates, Plato, and Aristotle exploring its meaning and importance.

One of the earliest recorded instances of the name Alethea can be found in Plato's dialogue "Cratylus," where it is mentioned as an example of a name that conveys the notion of truth. This philosophical work, written around 360 BCE, highlights the importance of accurate naming in Greek culture.

Throughout history, several notable figures have borne the name Alethea. One such individual was Alethea Brewster (1624-1689), an English Puritan who immigrated to Massachusetts and became one of the founders of the town of Dedham. Her name reflects the religious and philosophical values of the Puritan movement.

Another prominent Alethea was Alethea Howard (1590-1650), Countess of Arundel, an English noblewoman known for her patronage of the arts and her extensive collection of sculptures, paintings, and antiquities. Her name symbolized her pursuit of truth and knowledge.

In the realm of literature, Alethea Hayter (1911-2001) was a British writer and translator, best known for her translations of Russian literature, including works by Tolstoy and Dostoyevsky. Her name embodied her dedication to bringing the truth of these literary masterpieces to English-speaking audiences.

Alethea Garstin (1894-1978) was a British artist and writer, renowned for her portraits and landscapes. Her name reflected her commitment to capturing the truth and essence of her subjects on canvas.
