Cool factor: Crucifixion Cross “Anno Domini” Calendar
Artist: Stanley Ruiz
My take: The “Anno Domini” (AD) calendar cross refers to the Georgian calendar. On the ‘X-axis’ are months and days, while the ‘Y-axis’ keeps track of the date. Just fix the screws and you get a manual calendar in God’s abode.
