I’ve only read one Matthew Plampin book – Mrs Whistler, about the life of Maud Franklin, the model and muse of the artist James McNeill Whistler – so I was intrigued by the description of his new one, which is set in an entirely different time and place. These Wicked Devices takes us to Rome in the summer of 1650 and introduces us to three separate characters whose stories become entwined in various ways.
First, we meet Sister Orsola, a Benedictine nun who has fled to Rome after the city of Castro, including the convent that was her home, was razed to the ground on the Pope’s orders. Orsola is accompanied by Sister Serafina, a choir nun who goes into trance-like states where she endlessly recites the lives of the saints. In the final hours before Castro’s destruction, the Mother Abbess had asked Orsola to protect Serafina and help her find another convent where she could live in safety. Orsola agreed, hoping that performing this task would help her to atone for the sin of giving birth to a child who died unbaptised.
Another thread of the novel follows Donna Olimpia Maidalchini, the most important woman in Rome. As the sister-in-law of Pope Innocent X, she is regarded as the real power behind the papal throne, involving herself in politics and the appointment of positions within the church. At the beginning of the novel, Donna Olimpia is negotiating with France to help a French invasion force seize the Kingdom of Naples from Spain.
Finally, we meet Juan de Pareja , newly arrived in Rome from Spain. Juan is an assistant and slave of the Spanish artist, Diego Velázquez, who hopes to paint a portrait of the Pope. When Juan discovers some secret papers hidden inside a metal statue, however, he suspects that there’s also another reason for their presence in Rome.
These three storylines alternate throughout the book, clearly marked with the Latin headings Sorores (sisters), Domina (mistress) and Servus (servant), to indicate whose perspective we’ll be reading from next. The three do merge together a lot, but I did find myself preferring one over the others – the one about Sisters Orsola and Serafina. There’s a real sense of danger as they are suspected of being heretics due to their connection with Castro and Orsola isn’t sure who can and can’t be trusted as she tries to carry out her promise to the Abbess. There was a lot to interest me in Juan de Pareja’s story as well – his relationship with his master, Diego Velázquez, his own ambitions of becoming an artist and his desire to live his life as a free man – but I found Donna Olimpia’s sections less engaging, maybe because she herself is much less likeable as a person.
Plampin creates a strong sense of time and place, with vivid descriptions of the piazzas, fountains, palazzi and churches of Rome as the city bakes in a late spring heatwave. I found the writing style quite dry, though, so for me this was an interesting read rather than an entertaining one. Still, it was good to add to my knowledge of a period in Rome’s history that I knew very little about.
