Eusebius, a historian and bishop of the coastal city of Caesarea, in Palestine, assembled Christian writings in the local library. He also devised a system of cross-references, known as “canon tables,” that enabled readers to find parallel passages in the four Gospels—a system that the scholar James O’Donnell recently described as the world’s first set of hot links.

Further, while the notion of ‘steps’ is often used in education as a way to scaffold knowledge, in the case of the Australian Aboriginal memory technique, there is also literal use of the term ‘steps’ as the following quote highlights: “[w]alking around and looking at the trees was a good visual tool to relate to corresponding steps in the cycle”. Kelly [1, p. 20] concurs and refers to the way Indigenous cultures use geography and landscape to create “memory spaces” and even “narrative landscapes”.
