    Liturgical calendar for June 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 June marks the following holy days:

    11 June, Feast of Saint Barnabus the Apostle ‘Barnabe Aptle’, shown as a long-bearded man with an illustration of an archery target, though this seems unrelated to his martyrdom by stoning or any other episode in his life.

    17 June, Feast of Saint Botolph ‘Botulfi’, an abbot also sometimes called a bishop as depicted here with the Mitre of a bishop and the attribute of a tau shaped staff, a kind of crosier held by abbots and monastic saints. St Botolph is associated with Boston in Lincolnshire, East Anglia and Suffolk, but was a popular saint throughout medieval England.

    22 June, Feast of Saint Alban ‘Alban martred’ the first British Christian Martyr after whom the Hertfordshire town of St Albans is named. There is no portrait head representing St Alban, only the attribute of a club perhaps in reference to the torture he endured before being executed by beheading.

    24 June, Feast of Saint John the Baptist ‘Iohis bapte’ illustrated with a what may be a wing above his head denoting his role as a prophet of the ministry of Christ, also the crudely rendered figure of an animal likely intended to be a lamb the most common attribute of John the Baptist. The eve of the feast is also celebrated, it coincides roughly with the pre-Christian celebration of midsummer and is one of the ‘quarter days’ marking the changing of the seasons.

    26 June, Feast of Saints John and Paul ‘Iohis a pauli’ illustrated by the two heads of the saints atop one another beneath the symbol of an elaborate cross.

    29 June, Feast of Saints Peter and Paul the apostles ‘Petri a pauli aptole’ illustrated by the two heads of the saints beneath a key, the keys of heaven being the attribute of St Peter.

    30 June, the Commemoration of Saint Paul ‘Comemorato pauli’ illustrated by the head of the saint next to a sword referencing his martyrdom by beheading.

    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 30 in red at the top of the calendar indicates the number of day 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.
