What is "kalloor"

Kalloor is the name of the place in Tamil Nadu, India, where the Apostle Thomas, one of the 12 disciples of Jesus, is believed to have been killed. Though there are differing claims and no written accounts have been found to favor one over another, it is generally accepted that the Apostle Thomas arrived in what is now the state of Kerala and established a number of churches, converting mainly Brahmin families. He then traveled to what is now the modern state of Tamil Nadu and on to China, establishing small works along the way. After returning to Tamil Nadu, he was killed by some locals. Though he was buried in India, his body was taken, in the fourth or fifth century, to Edessa, in modern-day Turkey.
