The edition pages: the view options menu
If the text you are viewing is the edited Latin, then the view options menu will be available.
Variants are not visible by default, but when this option is selected, loci of variation will be shown in green, and moving the mouse over them will provide more detailed information.
Punctuation is shown in a modernised way by default, but a style more in keeping with the contemporary sources is available by selecting ‘Manuscript punctuation’
