IPA: //ˌdaɪəˈtɛsərɒn//
KK: /daɪəˈtɛsərən/
A written work that combines the four Gospels of the New Testament into one continuous story.
The diatessaron presents the life of Jesus in a unified narrative, making it easier to understand the events of the Gospels.
Diatessaron is derived from the Greek "dia-" (meaning through) and "tessaron" (meaning four). The term refers to a harmony of the four Gospels, thus conveying the idea of creating a unified account through the four distinct narratives.
Think of 'through' ('dia-') and 'four' ('tessaron') to remember that 'diatessaron' means a unified account created from the four Gospels.
