There are several reoccuring motifs in gaelic mythology. Recognizing of these motifs and how they are constructed will aid the filidh in remembering the many tales and legends required of them and allow them to present the beautiful tales at a moment's notice as they were required anciently.
A couple examples of the above mentioned motifs are:

1. Arming of the hero---The hero recieves his shield and sword and armor, usually from a female relative. Often times these weapons are magical in nature and ultimately aid in the victory or deed achieved.

2. The feast---Central to Celtic culture was the feast, where the lord or chief man gathered those warriors who served him to his house. Large portions of food and drink along with merrymaking usually are demonstrated in the motiff. This is also an opportunity to elaborate about guests, their skills, abilities, as well as social standing.

3. The mustering of a host---Naming of the great champions of an army and those warriors who follow them. Many times this is tied to another popular motif of Gaelic literature the naming of the banners. This is a description of each warrior and his personal banner, often times elaborating on the noble deeds and achievements that are represented by the symbols on the banners.

Many more motiffs are present in the varied examples of gaelic poetry and literature that are also used to construct basic settings within a tale. These shall be touched upon at a later date.
