    Liturgical calendar for February from a medeival almanac, marking important festivals in the Christian calendar, with a sideways portrait head of the saint against their feast day, along with an attribute identifying them. Ruled and illustrated in red, green, blue and black- brown inks.

    The liturgical calendar for February marks the following holy days:

    2 February, the purification of the blessed Virgin Mary, or Candlemas, ‘Purific Mar’. Illustrated with the crowned head of the Virgin Mary, Queen of Heaven, and a green fleur-de-lis representing the lily for her purity and virginity.

    3 February, Feast of Saint Blaise ‘Blasii epi’ [episcopal], a physician and Bishop of Sebastea shown with the mitre and crozier of his office.

    5 February, Feast of Saint Agatha virgin and martyr ‘Agathe virgo’ [virgin]. Illustrated with the head of the saint surmounted by a palm of martyrdom, a green tree or branch with red fruits, representing virginal purity and martyrdom.

    14 February, Feast of Saint Valentine ‘Valentini mr.’ [martir]. Illustrated with a bearded portrait of the saint with short curly hair, beneath an aspergillum, a sprinkler for casting holy water.

    16 February, Feast of Saint Juliana of Nicomedia, virgin and martyr ‘Juliane vigo’, shown with long hair beneath a faded palm of martyrdom; a green tree or branch with red fruits, symbol of her virginal purity and martyrdom. Sant Juliana was popular in the middle- ages as patron saint of sickness.

    22 February, Feast of the Chair of Saint Peter, apostle and Bishop of Rome, ‘Cathedra fet’. Illustrated by the head of Saint Peter with typical short beard and an elaborate, conical papal tiara. Above on the left his bishop’s throne or ‘cathedra’ in profile, and on the right a key representing the keys of to the kingdom of heaven.

    24 February, Feast of Saint Matthias the apostle ‘Mathie aplie’ curly- haired and bearded with a palm of martyrdom.

    The preceding columns of data for each day are populated with the dominical letter (by which the day of the week could be identified for a given year, relative to one known day) and by numbers written in a cipher formed of a circle (10), bracket (5) and dot (1). Arabic number 28 in red at the top of the calendar indicates the number of days in the month.
    Object history
    Robert Moray FRS donated the manuscript to the Royal Society library in 1668 (JBO/3/104: Journal Book, vol. 3 p.232). The provenance of the manuscript, before it came into the hands of Moray, is unknown.

    The presence of the feast day ‘Translacio Edwardi Regis’ (13 October) entered on the calendar as a red letter day shows an importance being attached to Edward the Confessor great patron of Westminster Abbey where his relics were a popular site for pilgrimage, this may suggest a London origin. While the inclusion of ‘Translacio Mildride’ (13 July) honouring the Anglo-Saxon princess Mildred, suggests Kent. Mildred was Abbess of Minster-in-Thanet, where she was first buried and her relics were later moved to Canterbury. Four Archbishops of Canterbury also feature in the liturgical calendar, strengthening the connection with Kent as a possible place of origin. The inclusion of cultivation activities early in the annual calendar of labours (digging/planting in February), a later hay harvest (July rather than June) and viticulture (March and September) suggests a temperate southern English climate in support of one of these locations rather than a warmer Mediterranean location or a cooler northern one.

    The calendar has been dated to the late 14th century based on the textual content and analysis of the pigments used. Saint George’s feast (23 April) written into the calendar in brown-black ink demarcating it as a lesser feast, indicates the calendar was produced before the elevation of the feast to a red letter day after the battle of Agincourt in 1415. Whilst the presence of the feast of St. Anne, which was not promulgated until 1383 suggests this as the earliest likely date. The presence of the yellow pigment orpiment supports a date in the late 14th century as it was widely replaced by use of lead-tin Yellow around 1400.

    An example of a mid-quality almanac. The range of pigments used demonstrate it was produced economically but not with the cheapest available materials. No gold leaf is present and indigo dyes are used for blue rather than more expensive minerals, however vermilion red is employed over cheaper organic sources. The uniformity and selection of pigments (gallo-tannic black rather than carbon-based) suggests that there was a single creator, rather than a scribe and an illustrator as would be expected for a finer document. This is borne out by the fairly crude rendering of the illustrative material and mistakes or omissions in the layout of information, see for example figures missing feet where these would have extended below a ground line and numbers missing from zodiac headings.
