Ambrogio Lorenzetti, The Entombment of Jesus

First half of the 14th century
Pinacoteca Nazionale di Siena

Given the horizontality and the kisses, this image has most of the features of medieval Entombments. But the action appears to take place just after the body has been removed from the cross, the moment of the Pietà, and there is no sarcophagus.

The way the museum has hung these panels suggests that they were once part of a single piece with SS. Martha and Mary flanking the Madonna above and mourning the dead Jesus below.
The woman kissing Jesus' hand is identified in her halo as St. Martha. Her sister St. Mary Magdalene is her kissing the feet; the inscription on the halo is faint but seems consistent with a reading of MAGDALENA. The kissing of the feet echoes her bathing those feet with her tears in Luke 7:38 and embracing them in numerous Crucifixion images. In the panels above this predella the same two sisters flank the Madonna and Child.

Other Crucifixion images of this century have the Magdalene raising her arms in anguish, a gesture echoed by the woman kneeling between the two sisters. (Her halo is inscribed only with stars.) A slightly later Entombment by Simone Martini also has the gesture cloned onto Mary Magdalene's fellow mourners.
