Runic Almanacs.
When the northern nations were converted to Christianity the old Pagan Festivals were changed to Christian holidays, and the old Pagan divinities were replaced by Christian Saints. The faith placed in the early deities was transferred to the latter. As certain deities had formerly been supposed to exercise influence over the weather and the crops; so the days dedicated to them, were now dedicated to certain Saints.
The days thus dedicated were called Mark-days, and as it may be supposed it became the office of the Clergy to keep account of the time and to calculate when the various holidays would occur.
Owing to the fact that many Christian feasts are what are called movable, that is, are not fixed to a certain date but depend on Easter, the reckoning was more difficult for the laity than it had been in Pagan times.
In those days the fixed holidays could be easily remembered. An ordinary man without knowing how to read or write could keep a list of them by cutting marks or notches on strips of wood.
The successors of these are called Messe, and Prim Staves. The Messe staves are the more simple—Messe-daeg means Mass day, and the stave only denoted such days. The Prim stave contained besides the marks for Sundays and the moon's changes. Hence their name from Prima-Luna, or first full moon after the equinox. The Messe-daeg staves are frequently met with. They consist generally of flat pieces of wood about a yard or an ell long, two inches wide, and half an inch thick, and have frequently a handle, giving them the appearance of a wooden sword. The flat side is divided into two unequal portions by a line running lengthways. In the narrow part, the days are notched at equal distances, half the year on each side, or 182 marks on one side and 183 on the other. In the wider space and connected with the days are the signs for those which are to be particularly observed: on the edges the weeks are indicated. The marks for the days do not run from January to July and from July to December, but on the winter side (Vetr-leid) from October 14 to April 13, and in the summer side (Somar-leid) from April 14 to October 13. The signs partly refer to the weather, partly to husbandry, and partly the legends of the Saints. Seldom are two staves formed exactly alike. Not only do the signs vary but the days themselves. Nor are they always flat, but sometimes square, i.e., with four equal sides: when of the latter shape they are called clogs, or clog almanacs.
They are called Cloggs, i.e., Logg, Almanacks = Al-mon-aght, viz., the regard or observation of all the Moons, because by means of these squared sticks, says Verstegan, they could certainly tell when the new Moons, full Moons, or other changes should happen, and consequently Easter and the other movable feasts. They are called by the Danes Rim-stocks, not only because the Dominical letters were anciently expressed on them in Runic characters, but also because the word Rimur anciently signified a Calendar. By the Norwegians with whom they are still in use, they are called Prim-staves, and for this reason, the principal and most useful thing inscribed on them being the prime or golden number, whence the changes of the moon are understood, and also as they were used as walking sticks, they were most properly called Prim-staves.
The origin of these Runic or Clog-calendars was Danish (vide Mr. J. W. Bradley, M.A., Salt Library, Stafford). They were unknown in the South, and only known by certain gentry in the North. They are quite unknown in Ireland and Scotland, and are only known from the few examples preserved in the Museums.
Owing to the changes of custom in modern times these wooden perpetual almanacs have become quite superseded by the printed annuals.
The inscriptions read proceeding from the right hand side of the notches, are marks or symbols of the festivals expressed in a kind of hieroglyphic manner, pointing out the characteristics of the Saints, against whose festivals they are placed, others the manner of their Martyrdom; others some remarkable fact in their lives; or to the work or sport of the time when the feasts were kept.
Thus on January 13 the Feast of St. Hiliary is denoted by a Cross or Crozier, the badge of a Bishop.
