Throughout the New Testament of Sinaiticus the words are written continuously in the style that comes to be called "biblical uncial" or "biblical majuscule". The parchment was prepared for writing lines, ruled with a sharp point. The letters are written on these lines, without accents or breathings. A variety of types of punctuation are used: high and middle points and colon, diaeresis on initial iota and upsilon, nomina sacra, paragraphos: initial letter into margin (extent of this varies considerably).
