by Cupid, or Venus, Cupid and minor erotes were sometimes donated by wealthy sponsors, to serve both religious and artistic purposes. Cupid's roles in literary myth are usually limited to actions on behalf of Venus; in Cupid and Psyche, one of the stories within The Golden Ass, by the Roman author Apuleius, the plot and its resolution are driven by Cupid's love for Psyche ("soul"), his filial disobedience, and his mother's envy. Iconography Signs, context and symbols Images of Venus have been found in domestic murals, mosaics and household shrines (lararia). Petronius, in his Satyricon, places an image of Venus among the Lares (household gods) of the freedman Trimalchio's lararium. The Venus types known as Venus Pompeiana ("Venus of Pompeii") and Venus Pescatrice ("Venus the Fisher-woman") are almost exclusive to Pompeii. Both forms of Venus are represented within Pompeian homes of the well-off, with Venus Pompeiana more commonly found in formal reception spaces, typically depicted in full regalia, draped with a mantle, standing rigidly upright with her right arm across her chest. Images of Venus Pescatrice tend to be more playful, usually found in less formal and less public "non-reception" areas: here, she usually holds a fishing rod, and sits amidst landscape scenery, accompanied by at least one cupid. Venus' signs are for the most part the same as Aphrodite's. They include roses, which were offered in Venus' Porta Collina rites, and above all, myrtle (Latin myrtus), which was cultivated for its white, sweetly scented flowers, aromatic, evergreen leaves and its various medical-magical properties. Venus' statues, and her worshipers, wore myrtle crowns at her festivals. Before its adoption into Venus' cults, myrtle was used in the purification rites of Cloacina, the Etruscan-Roman goddess of Rome's main sewer; later, Cloacina's association with Venus' sacred plant made her Venus Cloacina. Likewise, Roman folk-etymology transformed the ancient, obscure goddess Murcia into "Venus of the Myrtles, whom we now call Murcia". Myrtle was thought a particularly potent aphrodisiac. As goddess of love and sex, Venus played an essential role at Roman prenuptial rites and wedding nights, so myrtle and roses were used in bridal bouquets. Marriage itself was not a seduction but a lawful condition, under Juno's authority; so myrtle was excluded from the bridal crown. Venus was also a patron of the ordinary, everyday wine drunk by most Roman men and women; the seductive powers of wine were well known. In the rites
