"Maundy Thursday" - The Last Supper

1325 Ugolino da Siena (Italian, Sienese, active 1315–30s) The Last Supper

Francesco Bassano the Younger (1563-1570) Last Supper

The word Maundy comes from the Latin word mandatum, which means "command." The command that this holy day refers to is the one that Jesus gave to his disciples during the Last Supper: A new commandment I give to you, that you love one another, just like I have loved you; that you also love one another. By this everyone will know that you are my disciples, if you have love for one another. — John 13:34–35
