Mannerism was outdated by Erardi's lifetime, but he probably became familiar with this style through studying paintings located in churches and collections in Malta.
[1] Erardi might have also been influenced by the works of Baroque artists such as Caravaggio,[2] Domenichino and Guido Reni.
He also had connections with Sicily, Naples and Rome which were secured by the Order of St. John and the church.
[1] Works by Erardi may be found in many church buildings throughout Malta and Gozo.
[1] Other paintings by Erardi may be found in the parish churches of Birgu, Birkirkara, Cospicua,[3] Kirkop, Mosta, Msida, Naxxar, Qormi, Qrendi, Safi, Sannat, Victoria, Gozo and Żurrieq, along with the Sanctuary of Our Lady of Mellieħa and in numerous other churches and chapels.
