This picture, circa 1600CE, is from Mughal India, with a poet reciting his poetry and holding misbaha, or prayer beads. Picture taken from Christies.
This 19th century book shows the misbaha to be as important as personal hygiene. The book is in the New York Public Library. However the tasbih or misbaha have 99, 33 or 11 beads with a “guard” bead (to represent the name of Allah that only camels know). The number of beads represents the names of Allah, as mentioned in the Quran. Thought to have been used since the 9th century as a mnemonic device to remember prayers in the Sufi sect.
Kombolói are worry beads, with a debated history. It is thought to be similar to prayer beads, some numbered 33 to match the years of Christ’s life but Greek Kombolói are traditionally made from an odd number of beads, usually a multiple of four plus one (eg- 3×4+1 or 4×4+1). Begleri are an open kombolói, usually with 5-7 beads. There is quite an art to using kombolói and begleri.
