Many of the Epistles have a Rococo theme, especially the pastorale pieces with a cast of gods and demigods from classical mythology.
Thus,  Epistle 25, "Blåsen nu alla (All blow now!)",
a short crossing of the Stockholm waterway to Djurgården, is peopled with billowing waves, thunder, Venus, Neptune, tritons, postillions, angels, dolphins, zephyrs "and Paphos's whole might", as well as water-nymphs splashing about the "nymph" – in other words, Ulla Winblad.

The principal figures, given that the Epistles focus on drinking and its effects, along with "nymphs", are Bacchus and Venus / Fröja, but the cast is wider, including:
Amaryllis – a nymph of the countryside (from Virgil's Eclogues)
Bacchus – god of wine and drinking
Charon – the ferryman of Hades, carrying souls to the place of the dead
Chloris / Flora – the nymph or goddess of springtime, flowers and growth
Clotho – one of the three fates, spinning the thread of human life (which is suddenly cut off)
Cupid / Astrild – god of desire and erotic love, Astrild being a late Nordic invention
Jupiter/Jofur – king of the gods on Mount Olympus, god of thunder
Morpheus – god of sleep
Neptune – god of the sea, accompanying the birth of Venus from the waves
Nymph – a (beautiful) female nature deity
Pan – god of wildness and rough countryside
Themis – Titaness of divine law and justice
Triton – messenger of the sea, accompanying Neptune
Venus / Fröja / Aphrodite at Paphos – goddesses of love
