Focus on this artwork and explain the abstract.
The Circumcision  is a painting of the Circumcision of Jesus by the Italian  Renaissance painter Luca Signorelli, in the National Gallery in London,  dated to c. 1490–1491.
The Circumcision was also the occasion of the naming of Jesus, and by this period the emphasis of Catholic devotion was on the Holy Name of Jesus. The work was commissioned by the local Confraternity of the Holy Name of Jesus for the altar of the Circumcision Chapel in the church of San Francesco, Volterra, where Signorelli was working for the Medicis.  Like many Renaissance versions of the subject it conflates it with the Presentation of Jesus by including at the rear Simeon.  The Renaissance art historian and artist Giorgio Vasari saw the painting and described it as damaged by humidity, the Child having been repainted by Il Sodoma. The painting was acquired by the National Gallery in 1882.
