Among ancient cards which are mentioned in connection with the Tarot, there are firstly those of Baldini, which are the celebrated set attributed by tradition to Andrea Mantegna, though this view is now generally rejected. Their date is supposed to be about 1470, and it is thought that there are not more than four collections extant in Europe. A copy or reproduction referred to 1485 is perhaps equally rare. A complete set contains fifty numbers, divided into five denaries or sequences of ten cards each. There seems to be no record that they were used for the purposes of a game, whether of chance or skill; they could scarcely have lent themselves to divination or any form of fortune-telling; while it would be more than idle to impute a profound symbolical meaning to their obvious emblematic designs. The first denary embodies Conditions of Life, as follows: (1) The Beggar, (2) the Knave, (3) the Artisan, (4) the Merchant, (5) the Noble, (6) the Knight, (7) the Doge, (8) the King, (9) the Emperor, (10) the Pope. The second contains the Muses and their Divine Leader: (11) Calliope, (12) Urania, (13) Terpsichore, (14) Erato, (15) Polyhymnia, (16) Thalia, (17) Melpomene, (18) Euterpe, (19) Clio, (20) Apollo. The third combines part of the Liberal Arts and Sciences with other departments of human learning, as follows: (21) Grammar, (22) Logic, (23) Rhetoric, (24) Geometry, (25) Arithmetic, (26) Music, (27) Poetry, (28) Philosophy, (29) Astrology, (30) Theology. The fourth denary completes the Liberal Arts and enumerates the Virtues: (31) Astronomy, (32) Chronology, (33) Cosmology, (34) Temperance, (35) Prudence, (36) Strength, (37) Justice, (38) Charity, (39) Hope, (40) Faith. The fifth and last denary presents the System of the Heavens: (41) Moon, (42) Mercury, (43) Venus, (44) Sun, (45) Mars, (46) Jupiter, (47) Saturn, (48) Eighth Sphere, (49) Primum Mobile, (50) First Cause.
