Small hole on the canvas.
"The interesting perspective rendering and the imaginative inventiveness in the construction of the architectural backdrop mean that the work in question can be attributed to Francesco Maglioli, a 17th century Neapolitan painter with scant biographical information. In a glimpse of classical ruins, figures stand out with measured gestures and draped robes examining the remains of glorious times past. The classicism that emerges from his paintings is the composite combination of soft colours, sharply cut shadows and acute study from life, common traits of the works in his small catalogue. Maglioli confirms his ability to create complex architectures, taking care to give shape to even the most particular finishes, demonstrating refined technical expertise ." ASOR Studio
