Count Eustachy Tyszkiewicz, Leliwa coat of arms, was a Polish noble from the Tyszkiewicz family. He was an archaeologist and historian of the former Grand Duchy of Lithuania and White Ruthenia, then part of the Russian Empire. He is considered the first archaeologist to have undertaken a systematic study of historical sites in Belarus and Lithuania, and was highly influential on succeeding generations of archaeologists. In 1855 he founded the Museum of Antiquities in Vilnius, which is regarded as the predecessor institution of the National Museum of Lithuania. He donated his personal collection of archaeological and historical artifacts to start the museum. He was a younger brother of historian Konstanty Tyszkiewicz.
Eustathios Makrembolites, Latinized as Eustathius Macrembolites, was a Byzantine revivalist of the ancient Greek romance, flourished in the second half of the 12th century CE. He is sometimes conflated/equated with his contemporary, the Eparch of the City Eumathios Makrembolites.
Eustathius of Cappadocia, was a Neoplatonist and Sophist, and a pupil of Iamblichus and Aedesius, who lived at the beginning of the 4th century CE. When Aedesius was obliged to quit Cappadocia, Eustathius was left behind in his place. Eunapius, to whom alone we are indebted for our knowledge of Eustathius, declares that he was the best man and a great orator, whose speech in sweetness equalled the songs of the Sirens. His reputation was so great, that when the Persians besieged Antioch, and the empire was threatened with a war, the emperor Constantius II was prevailed upon to send Eustathius, although he was a pagan, as ambassador to king Shapur II, in 358, who is said to have been quite enchanted by his oratory. His countrymen and friends who longed for his return, sent deputies to him, but he refused to come back to his country on account of certain signs and omens. His wife Sosipatra is said to have even excelled her husband in talent and learning. They had three sons, one of which, Antoninus, also became a philosopher.
Eustratius of Nicaea was Metropolitan bishop of Nicaea in the early 12th century. He wrote commentaries on Aristotle's second book of the Analytica Posteriora and the Ethica Nicomachea.
