4to. Gothic type, 33 lines. 8 unnumbered ff. Modern half calf with marbled boards and gilt-stamped title to spine.
Probably the first separate edition of the 'Canones', taked from Astesanus de Ast's principal work, the 'Summa de casibus conscientiae'. GW cites an undated Leipzig edition, as well as the Vienna edition printed the following year. A specialty of this present printing is its simultaneous use of a woodcut title line together with letter printing on fol. 1, "an experiment not found elsewhere" (BMC).
Traces of a small, obliterated stamp on t. p., otherwise a very fine, well-preserved copy in an attractive binding.
