Tiberinus

This is how I imagine Tiberinus would have looked. I'm not sure who the actual statue is meant to be (it was taken in the gardens out the front of a castle built by the mad king Ludwig on an island in the middle of a lake in Bavaria), but it has the kind of wild sollemnity that Virgil describes in these lines from Aeneid VIII:

Huic deus ipse loci fluvio Tiberinus amoeno
populeas inter senior se attollere frondes
visus; eum tenuis glauco velabat amictu
carbasus, et crinis umbrosa tegebat harundo.
tum sic adfari et curas his demere dictis:

'O sate gente deum, Troianam ex hostibus urbem
qui revehis nobis aeternaque Pergama servas,
exspectate solo Laurenti arvisque Latinis,
hic tibi certa domus, certi (ne absiste) penates.'

To this man [Aeneas] the god of that place, old Tiberinus himself, appeared, lifting himself up from his hallowed stream, between the poplar leaves; a thin linen garment cloaked him with its grey-green mantle, and a clump of shady reeds hid his hair. Then the god spoke to him, and took away his worries with these words: 'O seed of the race of the gods, you who brings back to us the Trojan city, and who preserves eternal Pergumum, long-awaited on Laurentine soil, and in the Latin fields, here is a fixed home for you, here (fear not) are your fixed gods.'

[Aeneid VIII.31-39]
