About Confucius' Ta-Hio In many books about Confucius' Analects, 大學 is transliterated as Ta-Hio.

Why is this? 大學 is dàxué in Pinyin, da hsüeh in Wade-Giles, da sywe in Yale, and daai hok in Cantonese, so where does this transliteration come from?
It's Mandarin transliteration by Portuguese Jesuit Fr. Inácio da Costa (17th century).
