This is the translated title of a thin block-book of ten leaves, which was intended to explain the Lord’s Prayer by illustration. The blocks are printed in brown ink on one side of the paper. The _Exercise_ is in the popular form of dialogue. In the illustration No. 1, the monk _Frater_ begs the angel _Oratio_ to teach him the Lord’s Prayer. And these are the lessons that are taught: 2. _Our Father who art in Heaven._ Christ, the Monk, and the Angel kneel. 3. _Hallowed be thy name._ The Monk, the Angel, Christ, and the Church represented by a female figure, are kneeling. On the right the Virgin and Holy Child. 4. _Thy kingdom come._ A representation of Purgatory: in the upper part, the wicked surrounded by flames; in the lower part, Jews and Pagans in the fiery lake. 5. _Thy will be done._ The Almighty in the clouds, and before him the Angel and the Monk kneeling. On the right, a good Christian and an Angel. In the centre, two bad men who are rejecting the Eucharist. In the foreground, the Jews and Pagans throw down the cup and are pouring out its contents. _Scroll in No. 5._ Frater and Oratio kneeling before God. ‹f›Fiat voluntas tua sicut in cœlo et in terra.‹/f› Let Thy will be done in Heaven as on earth. . . . _The Angel to the right._ ‹f›Qui stat videat ne cadat.‹/f› Let him who may stand take heed lest he fall . . . _The Good Christian._ [p223] ‹f›Gratia Dei sum id quod sum.‹/f› Thanks to God that I am what I am. . . . _The Jews._ ‹f›Quis est Jesus filius fabri?‹/f› Who is Jesus but the son of the carpenter? _The Pagans._ ‹f›Quis noster dominus est?‹/f› Who is our Lord? . . . . _The Bad Christians._ ‹f›Ducamus in bonis dies nostros.‹/f› We guide ourselves to salvation. 6. _Give us this day our daily bread._ In the centre, three loaves of bread on a table, around which is Charity, robed as a queen, with three other figures. On one side the Monk and Angel kneeling; on the other, a Knight in armor. 7. _Forgive us our trespasses._ Christ standing on the altar, the blood pouring from his side in a basin, from which several persons fill their cups. 8. _Lead us not into temptation._ The disobedient, proud, gluttonous and avaricious surround a table. Death carries away the foremost. 9. _Deliver us from evil._ A representation of Hell. The disobedient man in the power of the Devil. The damned making supplication to the Almighty. 10. _Amen._ A view of Paradise, with the happiness of the blessed.
