This essay draws conclusions from a quantitative analysis of the thousands of lead tablets from Dodona published by Dakaris, Vokotopoulou and Christidis in 2013. It argues that the use of lead tablets in the divination process grew rapidly in the fifth century due to the increased availability of lead in particular from Attika. The tablets would have been left in visible locations after use before being cleared away to be ready for reuse after a period of time. This practice of displaying low-value metal objects is compared to the modern phenomena of coin-trees and love-locks. The use of tablets appears to decline rapidly through the fourth century, with few inscriptions dating to the period after 300 BCE. A number of explanations are offered: the monumentalization of the sanctuary in the third century making the practice of leaving tablets on display less acceptable; the changing role of the sanctuary leading to a change in clientele and consultation practice; and the need for lead for the construction of the large stone buildings resulting in the melting down of lead tablets, with more recent tablets being disproportionately affected.
