Sinaiticus
"The words are written continuously without separation and there are no accents or breathings, although high and middle points and colon are used for punctuation, initial Iota and Upsilon have the diaeresis and sacred names are abbreviated."

Vaticanus
"There is almost no punctuation, although initial Iota and Upsilon are marked with a diaeresis and sacred names are abbreviated."
