Today’s Google doodle celebrating St. Patrick’s Day includes a hidden word, but you have to know the ancient Irish ogham alphabet to decipher it.
Created by the Irish artist Ross Stewart, the doodle leads to a search for “St. Patrick’s Day.” The image depicts a traditional Irish scene, with a stonemason arranging rocks that spell out the name Google. The secret message written in ogham alphabet letters is carved into the large stone.
“Standing in for the Google ‘L’ is a tall stone that pays homage to Ireland’s earliest form of writing: ogham,” writes Google on the Google Doodle Blog, “The edge is marked with a series of ancient carvings, each group representing a letter of the ogham alphabet.”
Google shared the following early sketches of Stewart’s work for the St. Patrick’s Day doodle:
