In Latin:
nigra scuta, tincta corpora; atras ad proelia noctes 
legunt ipsaque formidine atque umbra feralis exercitus 
terrorem inferunt,
tincta corpora; atras ad proelia noctes
nullo hostium sustinente novum ac velut infernum

In English:
They wear black shields, their bodies are painted black, 
they choose dark nights for engaging in battle; and by 
the very awe and ghastly hue of their army, strike the 
enemy with dread, as none can bear this their aspect so 
surprising and as it were quite infernal.
their bodies are painted black, they choose dark nights 
for engaging in battle;
as none can bear this their aspect so surprising and as 
it were quite infernal.
