Nikolaos Oikonomides, focusing on 13th-century Byzantine literacy in Western Asia Minor, states that Byzantine society had "a completely literate church, an almost completely literate aristocracy, some literate horsemen, rare literate peasants and almost completely illiterate women." Ioannis Stouraitis estimates that the percentage of the Empire's population with some degree of literacy was at most 15–20% based primarily on the mention of illiterate Byzantine "tourmarchai" in the "Tactica" of Emperor Leo VI the Wise (r. 886–912). In Byzantium, the elementary school teacher occupied a low social position and taught mainly from simple fairy tale books ("Aesop's Fables" were often used). However, the grammarian and rhetorician, teachers responsible for the following two phases of education, were more respected. These used classical Greek texts like Homer's "Iliad" or "Odyssey" and much of their time was taken with detailed word-for-word explication. Books were rare and very expensive and likely only possessed by teachers who dictated passages to students. Women have tended to be overlooked in Byzantine studies as Byzantine society left few records about them. Women were disadvantaged in some aspects of their legal status and in their access to education, and limited in their freedom of movement. The life of a Byzantine Greek woman could be divided into three phases: girlhood, motherhood, and widowhood. Childhood was brief and perilous, even more so for girls than boys. Parents would celebrate the birth of a boy twice as much and there is some evidence of female infanticide (i.e. roadside abandonment and suffocation), though it was contrary to both civil and canon law. Educational opportunities for girls were few: they did not attend regular schools but were taught in groups at home by tutors. With few exceptions, education was limited to literacy and the Bible; a famous exception is the princess Anna Komnene (1083–1153), whose "Alexiad" displays a great depth of erudition, and the renowned 9th century Byzantine poet and composer Kassiani. The majority of a young girl's daily life would be spent in household and agrarian chores, preparing herself for marriage. For most girls, childhood came to an end with the onset of puberty, which was followed shortly after by betrothal and marriage. Although marriage arranged by the family was the norm, romantic love was not unknown. Most women bore many children but few survived infancy, and grief for the loss of a loved one was an inalienable part of life.
