In the Christian observance of Holy Thursday (that's today), church-goers re-enact the Last Supper (a Passover Seder) that Jesus held with his friends, his washing of their feet, and his final retreat to the Garden of Gethsemane to meditate and pray.
The Biblical writer Matthew (26:39) reports Jesus' prayer in the garden:
Nadezhda Mandelstam of whom I wrote extensively on Monday was culturally Christian as well as ethnically Jewish. Her memoir -- of life, of deaths, and of existence suspended in between for more than a decade during Stalin's regime of terror -- includes a poignant gloss on this prayer.
The "Agony in the Garden" is by Gauguin, painted in 1889.
