To the Greek Church he was always loyal. Its faith had glorified his youth, and to it he turned for strength throughout his solitary years. Its conventual discipline was dear to him, and oftener than of his birthplace at the foot of Mt. Olympus he dreamed of Mt. Sinai. On Mt. Sinai the Emperor Justinian founded the most revered of all Greek monasteries. Standing remote on its sacred mountain, the monastery depends on Cairo for its supplies. In Cairo, accordingly, there is a branch or agency which during the boyhood of Sophocles was presided over by his Uncle Constantius. At twelve he joined this uncle in Cairo. In the agency there, in the parent monastery on Sinai itself, and in journeyings between the two, the happy years were spent which shaped his intellectual and religious constitution. Though he never outwardly became a monk, he largely became one within. His adored uncle Constantius was his spiritual father. Through him his ideals had been acquired,--his passion for learning, his hardihood in duty, his imperturbable patience, his brief speech which allowed only so many words as might scantily clothe his thought, his indifference to personal comfort. He never spoke the name of Constantius without some sign of reverence; and in his will, after making certain private bequests, and leaving to Harvard College all his printed books and stereotype plates, he adds this clause: "All the residue and remainder of my property and estate I devise and bequeath to the said President and Fellows of Harvard College in trust, to keep the same as a permanent fund, and to apply the income thereof in two equal parts: one part to the purchase of Greek and Latin books (meaning hereby the ancient classics) or of Arabic books, or of books illustrating or explaining such Greek, Latin, or Arabic books; and the other part to the Catalogue Department of the General Library.... My will is that the entire income of the said fund be expended in every year, and that the fund be kept forever unimpaired, and be called and known as the Constantius Fund, in memory of my paternal uncle, Constantius the Sinaite, Kônstantios Sinaitnês."
