This document needs some fact checking - some the names of the churches are wrong. Also, the body of St. Thomas is in Ortona, Italy. There are some 1st class relics in India.
St. Bartholomew is said to have been skinned alive; thus the knife as his attribute...
I thought that the body of St Matthew was in the main altar of St Mary Major.
And the Evangelist Mark is in Venice (main altar cathedral).
I thought Matthew was killed by the sword.
