No-coverage answer
There is no information in the Taygetan contact material to answer this question. Hypatia of Alexandria — the Neoplatonist philosopher and mathematician murdered in 415 AD — is never mentioned in any transcript. While the material discusses the destruction of the Library of Alexandria as part of a systematic programme of historical erasure (Transcript 222), and identifies various historical figures as Taygetans or other extraterrestrials, Hypatia is not among them. The transcripts do not address whether she had any extraterrestrial connection.
