In the Western world, from the classical period through the early centuries of the Christian era, manuscripts were written without spaces between the words (scriptio continua), which makes them especially hard for the untrained to read. Extant copies of these early manuscripts written in Greek or Latin and usually dating from the 4th century to the 8th century, are classified according to their use of either all upper case or all lower case letters. Hebrew manuscripts, such as the Dead Sea scrolls make no such differentiation. Manuscripts using all upper case letters are called majuscule, those using all lower case are called minuscule. Usually, the majuscule scripts such as uncial are written with much more care. The scribe lifted his pen between each stroke, producing an unmistakable effect of regularity and formality. On the other hand, while minuscule scripts can be written with pen-lift, they may also be cursive, that is, use little or no pen-lift.
