September 21st is the Saints Day of Sant Mateu, which as the weather is still good, is an excuse for Festa Majors around Catalonia and the Catalan-speaking countries.
According to the New Testament, Sant Mateu or Saint Matthew the Apostle was born in Galilee in the first century BC and died either Ethiopia or Syria in the first century AD.
He is said to be the author of the Gospel According to Matthew, which was actually probably first written in Greek sometime later.
Matthew is venerated as a saint throughout the whole Christian world and is normally shown with a book or bag of money because his profession was apparently a tax collector.
