Detail of the entablature of the North Agora.
This image shows a roughed-out frieze block incorporated into the otherwise finished north portico. The fact that the detailed decorative carving does not carry on from the finished frieze block to the left onto this roughed-out block seems to indicate that all of this work was done before the blocks were put in place. The roughed-out block was presumably put up because it was needed in a hurry. It was also put in the wrong place since its decoration does not line up with the block next to it.
