Saint Prochorus of the Caves was a native of Smolensk, and entered the Kiev Caves monastery under the igumen John (1089-1103). He was a great ascetic of strict temperance. In place of bread he ate pigweed (or orach), and so he was called “pigweed-eater.” Every summer, he gathered pigweed and made enough bread from it to last him for a whole year. He also ate prosphora from church now and then, and his only drink was water. Seeing the patience of St Prochorus, God transformed the usual bitterness of the pigweed into sweetness.
