Prayer to Carmenta
Carmenta · Porrima · PostvortaA prayer for good dreams in the modern order; for the general explanation see carmenta-001.
It is addressed not to Carmentis but to the Camenae, in the plural. This is not a slip. The Camenae, Roman goddesses of springs and of song, were early identified with the Muses, and Carmentis was counted among them. The link runs through carmen — a word meaning both "song" and "spell", the very word from which her name comes.
Hence the logic of the request: a prophetic dream and a prophetic verse belong to one order for the Romans, and she who gives the song gives the dream too.
The card's English text expands this single line into a whole paragraph — an evil vision, a south wind to carry the dream away, a wish that the vision not prove prophetic. None of that is in the Latin, where the request is for exactly the opposite: dreams that are true.
