Lestovka

Lestovka (Russian: лeстовка) is a special type of prayer rope made of leather, once in general use in old Russia, and is still used by Russian Old Believers today, such as the Russian Orthodox Oldritualist Church, Pomorian Old-Orthodox Church and edinoverians.

The lestovka is traditionally constructed of leather, with "steps" made by looping leather around small twig sections. It has a total of 109 "steps" – small loops or knots, unevenly grouped. Lestovkas produced today are often made of vinyl or PVC, and the twig sections are today often replaced with rolls of paper, rubber or even plastic. Most lestovkas are joined to form a large loop, but the older variant, which is a simple rope unjoined at the ends, may still occasionally be found.

At the bottom of the lestovka hang four lapostki, which are flaps, usually triangular, but such variations as bell or oak-leaf shapes are not uncommon. These represent the four Gospels, and sometimes have icons, crosses, religious symbols or scripture verses printed or stitched on them, the stitching around these leaves symbolising the teaching of the Gospels. Simpler lestovkas will have the lapostki covered with silk brocade or velvet, and this is a traditional way of reusing church fabrics, either of vestments that have become too worn out for clergy to wear, or of altar-coverings and similar fabrics.

Between these lapostki are seven small movable pieces, usually tucked in securely and not visible unless the stitching between the lapostki is undone. These seven pieces represent the seven Mysteries (Sacraments) of the Church, their location between the leaves of the lapostki indicating their origin in and central relation to the Gospels.

Next, the main loop will have three large steps on either side where it joins the lapostki (in lestovkas that are joined together), and on the Lestovka itself are three more large steps, giving a total of nine, representing the nine months in which Christ was in the womb of the Theotokos (Blessed Virgin Mary), and also for the nine choirs of angels.
