They have published an interesting paper on Byzantine Pilgrimage Art by Gary Vikan (.pdf file)
"Within a few generations of the foundation of the Empire by Constantine the Great, the east Mediterranean had come alive with pious travelers.
Among the first was Constantine’s own mother, Helena, who, according to Eusebius, journeyed to the Holy Land at her son’s request to dedicate his newly-built churches located at the sacred sites identified with the Birth, Death, and Ascension of Christ-Bethlehem, Golgotha, and the Mount of Olives
Thousands were to follow in a mass mobilization of body and spirit which grew uninterrupted until the Arab conquest of the Holy Land in the seventh century."
There then follows descriptions of the main sites of pilgrimage:
all the holy places in Jerusalem including the Anastasis;
the main sites mentioned in the Gospels (Bethlehem, Nazareth, Cana, Samaria)
the main sites mentioned in the Old Testament (Mount Sinai, and the like)
the main sites mentioned in the Acts of the Apostles and the Epistles
Many of the sites of pilgrimage are now no longer to be seen. The churches and cathedrals built were works of art in themselves.
Detailed references are made to Egeria, an anonymous pilgrim from Piacenza (Italy), and other early pilgrims from the Early Church of whom written records and ccounts are still extant.
"But art was important on a modest scale, since the pilgrim, like the modern tourist, wanted something to take home with him. And while, as Egeria points out, many may have wished for a sliver of the True Cross, few could actually expect to receive such a prize; indeed the vast majority of our pilgrims was obliged to accept instead a eulogia or "blessing"."
The article then discusses the remaining examples of eulogia still extant.

Holy Women of Byzantium: Ten Saints' Lives in English Translation
edited by Alice-Mary Talbot
There are presented a wide variety of Byzantine female saints: nuns who disguised themselves in male monastic garb; a repentant harlot who withdrew to the desert for forty-seven years of self-imposed isolation; a nun who escaped from Arab captivity to spend thirty-five years as a hermit on the abandoned island of Paros; a wonder working abbess who slew a dragon; widows who found refuge in the ascetic life of the convent; married laywomen and a queen abused by their husbands.
