Allathea is in Origin.

Allathea is a rare variant of Alethea, a feminine given name from Greek aletheia, "truth," literally "unconcealment" (a- "not" + lethe "forgetfulness/oblivion"). The double-l spelling likely arose as an Anglicized elaboration alongside Alathea and Alithea, while retaining the same virtue meaning and classical pedigree.

In English use, Alethea/Alathea appears from the 17th century, favored by learned circles and Puritan taste for moral names; it is borne by Alethea (Alathea) Talbot, Countess of Arundel. The name saw modest revivals in the late 19th and mid-20th centuries in Britain and the United States and remains uncommon today. Close variants include Alethea (standard), Aletheia (near-Greek), Alethia and Aletha (American forms), Alathea and Alithea (archaizing spellings). Possible diminutives are Thea, Allie, and Letha. Allathea thus offers a distinctive yet meaningful route to the timeless theme of "truth."
