The great linguist Harold Williams was said to have spoken 58 languages. Is there somewhere that lists all the languages he spoke? Were his abilities limited to only European based languages, or also included Asian or African languages?

By the end of his life he had studied the bible in twenty-six languages, including Zulu, Swahili and Hausa. Before attending Christchurch and Timaru Boys' High Schools he had managed to teach himself Latin, Greek, Hebrew, French, German, Spanish, Italian, Maori, Samoan, Tongan, Fijian and other Polynesian dialects ... augmented no doubt by his acquisition of Finnish, Lettish, Estonian, Georgian, Tartar and a grasp of Russian grammar, better than most of his Russian friends. On his return from Russia he taught himself Japanese, Old Irish, Tagalog, Hungarian, Czech, Coptic, Egyptian, Hittite, Albanian, Basque, Chinese and mastered the cuneiform inscriptions and a book of 12,000 Chinese Mandarin characters.
