Irenicum amatoribus veritatis et pacis in Ecclesia Scoticana
Irenicum is a 1629 theological treatise on Church of Scotland controversies, written by John Forbes and printed at Aberdeen by E. Rabanus for readers concerned with church peace and doctrine. Its pictures are four decorative woodcut initial letters, I, S, P and S, each a large capital ringed with scrolling acanthus leaves, beasts' heads, and strapwork, which a designer could draw on for ornamental letterforms and border framing.
