Seventh edition, first published in 1474. One of his most famous works, the Kalendarium was an innovative calendar that predicted solar and lunar eclipses and calculated the day of the year in which, from 1477 to 1531, Easter would fall. In fact, the text was an updated compendium of the astronomic and mathematical knowledge of the time, and had an openly practical and teaching purpose. Lacking the second volvelle and string pointer, metal pointer missing from final woodcut. Top and bottom margin of title a little creased, a3-7 detached, woodcuts of instruments lightly soiled, light marginal thumb-soiling.
