The Schøyen Collection is “a means to preserve and protect for posterity a wide range of written expressions of belief, knowledge and understanding from many different cultures throughout the ages”; from the Introduction:
The Schøyen Collection comprises most types of manuscripts from the whole world spanning over 5000 years. It is the largest private manuscript collection formed in the 20th century.
The whole collection, MSS 1-5381, comprises 13,642 manuscript items, including 2,242 volumes. 6,850 manuscript items are from the ancient period, 3300 BC – 500 AD; 3,851 are from the medieval period, 500 – 1500; and 2,941 are post-medieval. There are manuscripts from 134 different countries and territories in 120 languages and 184 scripts.
The Contents page divides the collection into The Bible (The Hebrew and Aramaic Bible, The Greek New Testament and the Septuagint, The Coptic Bible translation, etc.), History, Literature, and Palaeography (The beginning of writing and the first alphabets, Greek book scripts, etc.); here, for example, is what they call “the earliest alphabetical writing known” (Canaanite West Semitic on bronze, Israel/Palestine, 18th – 17th c. BC). I don’t know how seriously to take their descriptions (they seem overenthusiastic about the possible age of the Australian objects), but the items themselves are remarkable and a pleasure to investigate. Thanks, David!
