Why did the scutum have a horizontal grip?

[Paulus Claudius Damianus]

Yes Valerius another language Mistake to me... Three feet is the total space for each soldier... (I wish you understand better like that...) Sorry. Rest the close fomation is the side shield to side shield. the shield close the spaces rank...

The hasta use like hoplite or under the shoulder is just one of a lot experience to show the inaccurency to the thrusting Hasta using...

I don't speak to the classical rectangular shield in Gladiatorial combat but in close formation in front battle line. This scutum can't be use like the lenticular scutum. The possibility use to the rectangular shield is really poor... Right, I know the Mirmillon fighting technic is really static. There are any mosaic to show gladiators Hurt the ennemy with the below part of his scutum in direct offensive hurt but it is not enought...
