1st thus nd (1980s) 35pp approx 5¼” x 3½” Acorn Catweasel. Half green cloth over marbled paper covered boards. VG+
 
A small format facsimile of The Heptameron or Magical Elements by Peter de Abano, (a set of rituals of conjuration, mapped out by day) reproduced from Robert Turner's 1655 first English edition of Agrippa's Fourth Book of Occult Philosophy. Unusual for Acorn in that it is a facsimile, rather than a typeset edition. No limitation listed but thought to be as low as 50 copies in total (hardback and paperback).
