Though it seems surprising to me that the Aztec Temple Mayor  had not been noticed before ,credit for its rediscovery goes to  the proto-anthropologist- archeologist Mr Manuel Gamio.  He seems like a thoroughl likeable man, I imagine him tipping his felt Homburg to las senoras as he crossed the Zocalo every day, his careful recording of the findings made with ink pen dipped into the  lovely ink set on his desk, and  his own hidden treasures, sweet for his grandchildren  waiting in an apothecary jar.
