Totem

The devil jumped for joy when Christ died; and by the very death of Christ the devil was overcome: he took, as it were, the bait in the mousetrap. He rejoiced at the death, thinking himself death’s commander. But that which caused his joy dangled the bait before him. The Lord’s cross was the devil’s mousetrap: the bait which caught him was the death of the Lord.

St. Augustine, Sermons, 261

Mendicant Resurrection Engine

A working ballista that shoots little paintings of dead monks into heaven (actually, across the room). It was inspired by a visit to the Capuchin Cemetery in Rome, where dried-out bodies of monks are propped up in catacombs, awaiting the Resurrection of the Dead.

Reaper (Sow the Gig; Reap the Whirligig)

This flying machine is either an angel of death or a soul harvester (I'm not sure which, but it's definitely weird and apocalyptic).

Bloodwheel-detail

Bloodwheel

[T]he blood of the martyrs is the seed of the Church.

Tertullian, Apologeticus, Chapter 50

The martyrdoms of Saints Catherine and Erasmus (Elmo) involved wheels: Catherine was tortured on a spiked wheel, while Erasmus was killed when his entrails were wrapped around a ship's windlass. This piece is a meditation on Tertullian's quote; the instruments of torture become a waterwheel. Palm branches are traditional symbols for martyrs.
