Arbor scientiae
Only partial translations or excerpts exist. This is the first complete English translation.
Extensive searches across multiple scholarly catalogs (including UNESCO Index Translationum, Open Library, and OpenAlex) confirm that while Ramon Llull's 'Arbor Scientiae' (The Tree of Science) is a foundational work in his corpus, no complete English translation exists. Scholarly literature and library records indicate that only partial translations, excerpts, and summaries are available in anthologies and academic studies. Therefore, this work remains a candidate for a first complete English translation.
