Origin of candela¹

C20: from Latin: candle

From the top of the Loma de Candela, a beautiful view of the valley below spreads out towards the south.

We then, guided by Candela, hurried forward on our journey, keeping a sharp look-out lest the fugitive Indians should return.

Of course the padre wished to know how it was I had found Candela; so I gave him a full account of all that had happened.

Candela now pushed on at a rapid rate, till we saw the light of our camp-fire a short distance off.

Calling Candela, he led him some way down the valley towards a grove of trees, among which were a great variety of creepers.
