In Saint Francis Receiving the Stigmata (Giotto), how is the Predella of the Description elucidated?
The predella shows three scenes from the saint's life: The Dream of Pope Innocent III, The Approval of the Franciscan Rule, and The Sermon to the Birds. These depictions are also generally attributed to Giotto, and are strongly tied to the frescoes of Assisi. The panel is signed OPUS IOCTI FLORENTINI ("The work of Giotto of Florence").
The Dream shows the collapse of Laterano, with its church tilting and a column just breaking. The presence of Saint Peter to indicate that the Pope is sleeping during the vision was an innovative technique at the time. The Approval, on the other hand, is very similar to Giotto's fresco in the Basilica of Saint Francis of Assisi  Innocence III Confirms the Franciscan Order and is placed in a similar room with arches and shelves to create perspective. The Sermon stands out for its simplicity and abstraction, thanks to its gold background without decorations. 
In general, the style of the scenes shows greater Gothic elegance than the three stories of the Fransciscan cycle in Giotto's Assisi frescoes and serves as a point of comparison to Giottesque artists such as the Master of St Cecilia.
