Three-faced Celtic deity (Lugus?) 1st-5th C. CE

"Make an estimate of the host for us,’ said Cú Chulainn to Lóeg, ‘that we may know their number.’ Lóeg did so and said to Cú Chulainn ‘I am confused. I cannot estimate exactly.’ ‘If only I come, I shall not see them confusedly,’ said Cú Chulainn. ‘Get out of the chariot,’ said Lóeg. Cú Chulainn got out of the chariot and for a long time he estimated the number of the host. ‘Even you,’ said Lóeg, ‘do not find it easy.’ ‘It is easier for me, however, than for you. For I have three gifts, namely, the gift of sight, the gift of understanding, the gift of reckoning. I have reckoned up the numbers here.

This is one of the three cleverest yet most difficult reckonings ever made in Ireland, the three being this reckoning of the men of Ireland made by Cú Chulainn in the Táin, the reckoning made by Lug of the Fomorians in the battle of Mag Tuired and the reckoning of the army in Bruiden Da Derga made by Ingcél."
