The Change of Faith on the Coins
Through systematic study of the changes in the coin imagery of the Kingdom of Aksum minted in different periods, archaeologists found that the coins of the early part of Ezana’s reign still bore traditional pagan symbols of sun and moon, thereafter gradually replaced by the Christian cross, and this historic change of coin imagery provided precious first-hand archaeological evidence for scholars to date his conversion to Christianity approximately, Aksum thereby becoming one of the earliest known regimes of sub-Saharan Africa to establish Christianity as the official faith.
The Obelisks of Aksum
The giant granite obelisks of the Kingdom of Aksum surviving to this day, the tallest about 33 meters high, are one of the tallest known single-stone monuments of the ancient world; these obelisks marked the underground tombs of members of the royal house, and the fineness and complexity of their carving and the skill of their transport and raising fully display the highly developed architectural engineering capacity of Aksumite civilization — one obelisk had earlier been looted by Italian colonizers and carried to Rome, and only in 2005, after much difficulty, was it returned to its original Ethiopian site and re-erected.
