Eustathius

Latinized form of Greek Εὐστάθιος (Eustathios), derived from the Greek word εὐσταθής (eustathes) meaning "well-built, stable". It is ultimately from εὖ (eu) meaning "good" and ἵστημι (histemi) meaning "to stand, to set up". This was the name of a few early saints, including the 2nd-century martyr also known as Eustachius (see Eustace).
