Analysis of Leonardo da Vinci's Tablecloth in The Last Supper Reveals Artistic Details

An examination of Leonardo da Vinci's The Last Supper (1495-1497) focuses on the detailed depiction of the tablecloth, revealing specific folds, dimensions, and decorative elements. The cloth measures approximately 5.4 by 1.3 meters with 17 longitudinal and 8-9 transverse folds, creating about 180 fabric layers when folded. It is identified as a Perugian tablecloth, a liturgical linen with blue decorative strips produced in Umbria since the 12th century. The tablecloth features a knotted detail at the ends, which may reference Leonardo's knot motifs or the ancient Egyptian Isis knot symbolizing divine connection. The analysis compares this depiction with other Renaissance artists' treatments of tablecloths in Last Supper scenes, noting Leonardo's unique attention to realistic detail.
