Pairing in art
Calling-of-apostles panels and Caravaggesque vocation scenes almost always show Peter and Andrew as a unit—compare their hands first.
What to look for
Keys (gold and silver) · Elderly bald or short-bearded man · Papal colors blue and gold
Quick recognition clue
Saint Peter: prioritize keys before guessing from beard type alone.
At a glance
Peter and Andrew were fishermen brothers called from the same nets. Peter receives the keys; Andrew carries the saltire cross of his martyrdom. Calling scenes and apostolic friezes pair them constantly—learning both prevents the most common confusion between keys and cross attributes.
Why start with this pair
Peter’s papal keys appear from Rome to parish churches worldwide; Andrew’s saltire cross became a national emblem. Together they establish the pattern—martyrdom attribute plus vocational symbol—that repeats across the other apostles in later modules.

Watch for confusion
Keys vs cross
Peter’s keys signify Petrine office; Andrew’s diagonal cross records his martyrdom at Patras—different theology, different silhouette.
Common mistake
Often confused with other bearded apostles holding books Andrew (brother; keys vs saltire)
Compare with
This lesson pairs Saint Peter and Saint Andrew. In side-by-side panels, attribute asymmetry resolves identity faster than facial type.
Historical notes
Protoclete
Andrew is titled “first-called” because he followed John the Baptist before bringing Simon to Christ—useful context when Andrew appears without Peter.
