In Sarojini Naidu’s poem In the Bazaars of Hyderabad, the merchants display their merchandise to which the poet comments:

Richly your wares are displayed.

The four items displayed here are crimson and silver turbans, purple brocade tunics, mirrors with amber-panel and daggers with jade handles.

Now, the word ‘richly’ suggests a number of things like the variety and colourfulness of the items, the precious fabrics and rocks like brocade, jade and amber, the rich decoration and design of the items and the rich cultural heritage of India. That is why the use of the word ‘richly’ is justified here.
