[1593].- [6], 60, [16] f.: il.; 19 cm. Junto com: PRIVILEGIA | CONGREGATIONIS | Stæ. MARIAE DE ALCOBATIA | CISTERCIENSIS | ORDINIS REGNORVM | PORTVGALLIAE. | [...] | Pars Prima.- Venetiis: Apud Gio. Dominicum de Imbertis, M. D. XCIII. [1593].- [12 ], 67 f.; 19 cm.- E. The copy of “Diffiniçoens” corresponds exactly to the collation indicated by António Joaquim Anselmo, although with some swapped sections: 1st section, [ ]//4; 2nd section, ***// 2 (Tavoada, whom Anselmo mentions at the end); 18 section A-S//4; section A//4. The last page of the first section (small engraving identical to the one on the title page, representing St. Benedict, with a blank verso), loose, a little shorter and with some stains. The final section A, excessively trimmed (shorter), features a full-page xilographic engraving on the back of the last page depicting a monstrance flanked by two angels. The last three sections (R, S, and A) comprise four briefs by Pope Clement VIII, relating to the Order. Volume somewhat trimmed with three old ownerships scratched on the title page of the first title. The second work, with the indication Pars Prima, corresponds to the BNP copy with the quotation F 1388. Ex-libris by Aníbal Fernandes Tomás and Victor d’Avila Perez (lot no. 2264 of the auction held in 1939/40). Interesting contemporary binding, entirely in sheepskin, with blind tooling decoration on the surfaces and gold decoration between the sections, tired, with serious faults in the cover and signs of wormholes on the spine; old(?) ownership scraped on the front cover. Anselmo, 28. BN (16th century), 537. Biblioteca de D. Manuel II, 317. The three copies of the BNP and the copy of D. Manuel II apparently do not include the section with the Tavoada.
