For the subject see the ' Aeneid' (4: 119). Dido & Aeneas are in the cave at the right; in the sky at the left Juno, Venus & Hymen. The figures & the dogs are by the Roman painter, Carlo Maratta, & the landscape by Dughet. The picture was recorded in the Palazzo Falconieri, Rome, in 1717 where it remained until around 1800.
