Roy later said that his first memory was of a day when his Zulu nurse maid, Catherine Mgadi, wheeled him further than usual on their morning outing. The hedge they had been skirting suddenly stopped and they came across an empty, railed in site overlooking the Indian Ocean, which a fascinated Roy glimpsed through the legs of a horse. Sensing Roy's fascination, Catherine told him that the Indian Ocean was ""Lwandhla"", the word for the sea in the Zulu language. Roy later recalled, ""Lwandhla", which in two-syllables, Homerically expressed the pride and glory of the ocean and the plunge of its breakers, struck my mind with a force which no other word or line in prose or poetry has ever had for me since. I went on repeating the word "lwandhla" for days. It was the first word I remember "learning"." In later years, both horses and the sea would be regular themes in Campbell's poetry.
