Stroiffi was born on 20 October 1616 in Padua as the son of the Flemish painter Giovanni who was then working in Padua. His father died before 1644 as is demonstrated by Ermanno's signature on the will of Bernardo Strozzi in that year. His mother Laura died on 12 September 1652. Not much is known about the artist's training. It is known he became an assistant in the workshop of Bernardo Strozzi. Strozzi was the leading painter in Venice in the first half of the 17th century and also a Capuchin monk. Stroiffi was Strozzi's favorite assistant and worked on many of the large commissions which Strozzi received. Stroiffi was also a beneficiary of Strozzi's will. Between 1645 and 1654 when he was still at the start of his career, Stroiffi travelled to various cities in central northern Italy. One of the cities was Mantua, the historic power base of the Gonzaga family, which was an important patron of the arts. He received commissions from the Ducal court. Other painters active at the court in Mantua at that time included Daniel van den Dyck, a Flemish artist who had moved to Mantua around 1657 and had become the court painter. In the 1650s Stroiffi participated in the cycle of the oratory of San Filippo Neri at the hospital of San Lazzaro dei Mendicanti in Venice. Stroiffi became a priest in 1647. He played an important role in the establishment of the Congregation of the Oratory in Padua and Venice.
Work
Ermanno Stroiffi was a versatile and prolific artist who worked on canvas and as a fresco artist. He treated a wide range of subject matter including religious, mythological and allegorical themes as well as genre scenes and portraits. Some of his compositions include still life elements. Religious compositions make up the majority of his works. The number of works attributed to the artist is limited as a good part of his production is still submerged in the countless paintings attributed to Strozzi and his workshop. His style was close to that of his master Strozzi. He gradually developed away from Strozzi's example and created powerful compositions through the use of shade. The relationship between the works of Stroiffi and Strozzi can be illustrated through the early work :File:Ermanno Stroiffi - Fruit vendor.JPG|Fruit vendor. The work was only recently attributed to Stroiffi after having been attributed to a painter in the circle of Strozzi. The work was created in Mantua during the years of Stroiffi's apprenticeship. The painting is derived from :File:Bernardo Strozzi - Fruit vendor.jpg|Strozzi's original. Stroiffi has reworked his master's model in line with his personal artistic preferences. The veil of the fruit vendor appears softened and the male profile reflects a model by Stroiffi, which reappears in a series of works recently attributed to the artist. Another difference between Stroiffi's and Strozzi's versions is that the fabrics in Strozzi's original are swollen and crispy while they are drooping and flat in Stroiffi's work. Stroiffi has also added more fruit and vegetables, showing his interest in the still life genre.
