Reminiscent of vévés perhaps overlapping the Ogham alphabet, these symbols are part of an elaborate calendar system. Can you identify their nature?
Here's the answer: pages from a prayer book reproduced in Leslie's Sunday Magazine throughout 1879. "The Calendar is that of the Anglican Prayer-book, in which the 'Days of Obligation,' here printed in heavy type, are distinguished from the 'Days of Devotion,' here printed in ordinary type. Only the 'Days of Obligation' are retained in the 'Book of Common Prayer of the Protestant Episcopal Church in the United States of America.' This being understood, the Calendar here given applies to both the Anglican and the American Prayer Books. A stands for Apostle; Abp. for Archbishop; B for Bishop; C for Confessor; E for Evangelist; K for King; M for Martyr; P for Presbyter; V for Virgin."
