Oil on canvas. Lombard school, late 16th century. In the large scene, an angel is depicted in the foreground announcing to Joachim, as he grazes his sheep, the impending birth of his daughter; in the background, Joachim meets and embraces his wife Anna, who is awaiting him at the gates of a city: according to tradition, the two spouses, considered sterile, after both receiving a visit from an angel, meet at the Golden Gate (of Jerusalem), symbolizing the beginning of salvation through the conception of Mary, the future mother of Jesus. The profile of the city in the background points to Cremona, probably the city of the patron of the work, where Giovan Battista Trotti, known as Malosso (1555-1619), a Mannerist painter, lived and worked, to whom the work is accustomed in style, allowing us to hypothesize an attribution to him or his workshop. The work, previously relined, shows slight loss of color. It is presented with a frame.
