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.
