the months of the year and the signs of the zodiac. Across these spaces are drawn six oblique hour-lines.
'To ascertain the time of day by the chilindre, consider what month it is, and turn the lid round till the style stands directly over the corresponding part of the chilindre; then hold up the instrument by the string so that the style points towards the sun, or in other words, so that the shadow of the style falls perpendicularly, and the hour will be shewn by the lowest line reached by the shadow.'
Another treatise of the same character was subsequently edited by Mr. Brock for the same Society. It is entitled 'Practica Chilindri; or the Working of the Cylinder; by John Hoveden.'
There is a curious reference to the same instrument in the following passage from Horman's Vulgaria, leaf 338, back:—'There be iorneyringis [day-circles, dials] and instrumentis lyke an hangynge pyler with a tunge lyllyng [lolling] out, to knowe what tyme of the day.'
In Wright's Vocabularies, ed. Wülker, 572. 22, we find: 'Chilindrus, anglice a leuel; uel est instrumentum quo hore notantur, anglice a chylaundre.' It thus appears that the reading kalendar, in the old editions, is due to a mistake.
The most interesting comment on this passage is afforded by the opening lines of the Prologue to Part II. of Lydgate's Siege of Thebes, where Lydgate is clearly thinking of Chaucer's words. Here also the black-letter edition of 1561 has Kalendar, but the reading of MS. Arundel 119 (leaf 18) is more correct, as follows:—
'Passed the throp of Bowton on the Ble,
By my chilyndre I gan anon to se,
Thorgh the sonne, that ful cler gan shyne,
Of the clok[ke] that it drogh to nyne.'
