"Sli an Eolais" ('The Way of Knowledge') is a collection of terms, proverbs, expressions, literary fragments and folklore, all thematically classified (for example, the human body, health, time and weather, children and family). "Eagna an Ghaeil" ('The Wisdom of the Gael') is a companion to "Sli an Eolais," which explains of the majority of the proverbs in "Sli an Eolais" as well as elucidating many expressions and observations on various aspects of life. These two books contain such an abundance of information and such richness of language, much of it forgotten, perhaps, that readers who absorb the contents of the two will will find their knowledge of Ireland and the Irish language greatly augmented. The books also provide a fascinating insight into the Ireland of the 1920s (when both books were published) and its distinctive characteristics-national pride, piety, and an awareness of Ireland's history and heritage."
