Ciriaco

Ciriaco is a male given name in Italian (pronounced [tʃiˈrjaːko]) and Spanish (pronounced: [θiɾiˈako]). In Portuguese, it's spelled Ciríaco (pronounced: [siˈrjaːko]).

It derives from the Greek given name Κυριακός (also Κυριάκος) which means of the Lord or lordly; from the Greek kύριος, kyrios: lord. Thus it is equivalent in meaning to the name Domenico.
