Alright, I'm stuck on one part near the end, beginning with line 9. This is the Latin. Below I'll give my translation.
Visendus ater flumine languido
Cocytos errans et Danai genus
infame damnatusque longi
Sisyphus Aeolides laboris.
I haven't been able to get past that. This is what I have:
Dark Cocytus wandering has been visiting the sluggish river
and ...
I know that Cocytus is a river, but the "sluggish river" is either dative or ablative, not nominative, so I'm struggling to find where that fits. Help?
Thank you!
