question not related to art (yet):
lately i have been reading the dionysiaca by nonnus and just yesterday i have reached the part in which actaeon's myth is told. nonnus makes acteaeon climb a tree in order to spy on artemis, and i wanted to ask - how popular is this element in this myth? because it is very clear that here nonnus intends to draw as many parallels between actaeon and pentheus as possible (as he should) and if i remember correctly in ovid there are no mentions of actaeon climbing a tree. does someone knows any other classical versions in which this element is present?
thank you in advance
