Relating to apographs or the nature of copied documents; describing a text that is a copy rather than the original.
From apograph + -ical (compound adjective suffix). This is the most formal variant of the adjective forms, often used in academic discourse.
When scholars say a text has only 'apographical evidence,' they're essentially saying 'we're working with a copy's copy,' which adds uncertainty but also makes the survival of texts through the centuries even more remarkable.
